How Do I Write an Apex Unit Test?

We can construct the regression:$$beginbmatrix y_1 y_2 endbmatrixbeginbmatrix x_1 & 0 x_2 & x_2 endbmatrixbeginbmatrix beta_1 Delta endbmatrixbeginbmatrix e_1 e_2 endbmatrix$$ When estimating the parameters, we should keep in mind that $sigma^2_1$ need not equal $sigma^2_2$, which introduces a simple, well-structured, heteroskedasticity into the estimation, which can be addressed via weighted least squares.The null hypothesis is $H_0: Delta 0$, and the alternative is, evidently, $H_A: Delta neq 0$. In the case of Gaussian errors, the obvious test is an $F$-test, which would be exact in finite samples if it were not for the likely mild) disruption caused by having to estimate two variance terms instead of one. To see how much of a disruption the heteroskedasticity causes to the distribution of the $F$-statistic, we construct an example with $n_1 n_2 100$ and four regressors in both $x_1$ and $x_2$. We set $sigma^2_2 4sigma^2_1$, and estimate the regression using iteratively reweighted least squares. We then calculate the p-value of the $F$-test, which, under $H_0$, should be distributed according to a Uniform distribution. Repeating the entire process 10,000 times allows us to test the distribution of the 10,000 p-values against the Uniform distribution, in this case using a Kolmogorov-Smirnov test:which indicates, at least in this case, that the $F$-statistic's distribution is pretty close to the theoretical distribution, even for a not-terribly-large sample size.In the case of non-Gaussian errors, it seems not unlikely that the $F$-test will break down, due to its known sensitivity to exactly this situation. In that case, an alternative would be to construct a permutation or bootstrap test (https://en.wikipedia.org/wiki/Resampling_(statistics)) based on the $F$-statistic, but I should point out that if you were to do so, there would likely be no particular advantage to sticking with the $F$-statistic as the test statistic of choice. An asymptotically equivalent permutation test can be applied if $n_1$ and $n_2$ together are too large for an exact permutation test; the asymptotics are such that the proper significance level is obtained (asymptotically) as long as exchangeability assumptions are met (and of course the null hypothesis is true.)You can also rely on the asymptotic distribution of the $F$-statistic under non-Gaussianity, as outlined here: Does the F-test for multivariable regression work with non-normal residuals but large sample size?. However, IIRC the power of the $F$-test can be severely affected even if its significance level is approximately correct, hence my recommendation for the use of a permutation-based test.This question is a follow-up to Testing equality of coefficients from two different regressions.Consider the two data generating processes $$y_1x_1'beta_1e_1$$ and $$y_2x'_2beta_2e_2$$ where $x_1$ and $x_2$ are vectors of the same length. Assume that $x_j$ is independent of $e_j$ for $j1,2$, and that we have two independent iid samples of sizes $n_1$ and $n_2$ from the first and second data generating process, respectively. Assume $n_1>n_2$ (or $n_1neq n_2$). For us to be able to use asymptotic theory for least squares I also assume that $E(y^4)Is there a test statistic whose asymptotic distribution is known under $H_0:beta_1beta_2$ as $n_1$ and $n_2$ diverges to infinity? I would like to use such a statistic to acquire an asymptotically valid test for $H_0$ against not-$H_0$. One idea is to consider a test statistic based on the first $min(n_1,n_2)$ observations (see comments).I believe the test statistics proposed in Testing equality of coefficients from two different regressions do not have known asymptotic distributions.I tried to use multivariate regression and SUR to create a test statistic, but could not derive relevant asymptotic results once $n_1neq n_2$.·OTHER ANSWER:This question is a follow-up to Testing equality of coefficients from two different regressions.Consider the two data generating processes $$y_1x_1'beta_1e_1$$ and $$y_2x'_2beta_2e_2$$ where $x_1$ and $x_2$ are vectors of the same length.

This problem can be solved by using the linearity of expectation again and again. I will give a complete illustration for part (a), but leave only hints part (b) as an exercise.Let the probability that each person has the condition is $p$ independently of each other. In your question, $p$ would be $0.02$. For part (a), let $X_i$ be the random variable that takes the value of $1$ if the $i$-th person tested has the condition. Clearly $E(X_i) p$. Then by the linearity of expectation,$$E(sum_1 le i le 150 X_i) sum_1 le i le 150 E(X_i) 150p$$And that answers part (a).For part (b), there are two things to calculate: the expected cost and the expected number of people who tested positive in both tests. To calculate the expected cost, define the random variable $Y_i$ to be the expected cost of testing the $i$-th person. What is $E(Y_i)$? What is $E(sum_1 le i le 2000 Y_i)$? Do a similar thing for the expected number of people who tested positive in both tests, and you will get your answerTwo percent of the population has a certain condition for which there are two diagnostic tests.Test A, which costs $1 per person, gives positive results for 80% of persons with the condition and for 5% of persons without the condition.Test B, which costs 100$ per person, gives positive results for all persons with the condition and negative results for all persons without it.(a) Suppose that test B is given to 150 persons, at a cost of 15,000$. How many cases of the condition would one expect to detect?(b) Suppose that 2000 persons are given test A, and then only those who test positive are given test B.Show that the expected cost is $15,000 but that the expected number of cases detected is much larger than in part (a).Hey I've been currently stuck on this question for a bit, but I don't know which formula to use at the beginning. If anyone can just point me in the right direction it'll help a lot! thanks :)·OTHER ANSWER:Two percent of the population has a certain condition for which there are two diagnostic tests.Test A, which costs $1 per person, gives positive results for 80% of persons with the condition and for 5% of persons without the condition.Test B, which costs 100$ per person, gives positive results for all persons with the condition and negative results for all persons without it.(a) Suppose that test B is given to 150 persons, at a cost of 15,000$.

That's because you did not label your properties as public (you don't have an access modifier at all) in your class. I am going under the assumption that you wanted these List to be accessible publicly.If you do this:they will be accessible in your test class. If it is not meant to be visible i.e. private, you should specify it as such with the keyword private and you can use the @TestVisible annotation as suggested. However this should be a last resort!Before you do that however, you should do the following:If you cannot find a way to populate your private properties, after you have exhausted all options, then you can use the @TestVisible annotation.Here would be an example:Can any one help me on this Error as **Variable is not visible** in a test class.Any help very much appreciated.Code : public with sharing class InvoiceController List appointmentList get;set;//These three lines are not List appointmentList1 get;set; //covered in test class public list addressget;set;//Test Class :InvoiceController icwc new InvoiceController(sc); icwc.appointmentListicwc.getappointmentList(); icwc.appointmentList1icwc.getappointmentList1();The system throws an Error as :Variable is not visible: appointmentList icwc.appointmentListicwc.getappointmentList();Similarly for the otherVariable is not visible: appointmentList1 icwc.appointmentList1icwc.getappointmentList1();·OTHER ANSWER:Can any one help me on this Error as **Variable is not visible** in a test class.Any help very much appreciated.Code : public with sharing class InvoiceController List appointmentList get;set;//These three lines are not List appointmentList1 get;set; //covered in test class public list addressget;set;//Test Class :InvoiceController icwc new InvoiceController(sc); icwc.appointmentListicwc.getappointmentList(); icwc.appointmentList1icwc.getappointmentList1();The system throws an Error as :Variable is not visible: appointmentList icwc.appointmentListicwc.getappointmentList();Similarly for the otherVariable is not visible: appointmentList1 icwc.appointmentList1icwc.getappointmentList1();

Update: @Skylinerw has commented that this will bug on multiplayer. To fix this, just ad the team selector for each command and as long everyone has there own team, everything should be fine. You can always ally teams. For this example I am using team a called team. Also, instead of teams, you can use the tag name%% where %% is the name.Update: for a better reset machine, remove the torch and place a block in its spot than a repeater touching the comparator. Make sure to set the clock at its slowest speed (press 3 times) and is connected to the string of Redstone that connects to the final command block.I have a different method to this. (This is an edit of Dragnoz's video's method)/The first command block tests for an item. In this case, I used dragnoz's command:This is the effect command. You can customize it, but here I gave made it so that when I use the Poisoned Blade, all entities in a range of 16 except for players get effect 2 (slowness) for 13 seconds which is level 2. The first three blocks to the left reset the comparators to off.Then we have a clock running these commands 24/7Then we have 1CB, followed by a comparator, 2CB followed by a comparator, 3CB, followed by a comparator.Then at the end of the comparator we have a redstone string that inputs a signal to a redstone torch.The redstone torch is connected to a wire of redstone which goes to a command block that resets the scoreboard (/scoreboard players set @pscore_damage_min1 damage 0) so the command can operator more than one time. You can do all sorts of stuff with the execute command, one of my favorite being that you when you replace the effect slowness with heal. In a nutshell it tests if you are holding (in slot 0) A sword named Poisoned blade > then it tests if you have done damage > finally it executes a command (effect) and then resets the score for further use.I'm not the most experienced person when it comes to commands. I worked out how to do stuff like when holding x you have y effect. I wanted to think of something that gave other people an effect when hit.

Although GPR has been widely used in hydrology, engineering, environment and other fields, many basic theoretical and technical problems have not been fundamentally solved, so the real advantages of GPR have not been brought into full play.The main problems existing in GPR technology include:1) The detection depth is shallow, and the contradiction between detection depth and resolution cannot be overcome. Increasing detection depth means sacrificing detection resolution;2) Multiple spread and other clutter jamming are serious, and there has been no good elimination method, which exists in radars at home and abroad;3) The influence of medium unevenness is great and can not be eliminated, resulting in difficulty in obtaining necessary velocity data;4) The data collection method of single sending and single receiving can provide limited information for post-processing and interpretation.The above problems are fatal defects for GPR. Although many geophysicists, electromagnetic experts and geophysical workers have done a lot of research and improvement on radar antenna design, signal processing and underground target imaging, these works are only partial modifications to the existing GPR system. In order to develop GPR technology, we must update our ideas and solve the problems from the fundamental principle.In view of this situation, experts proposed to develop a new GPR system - phased array GPR detection system in 1999.The basic research idea is to replace the current monopole radar antenna with the phased array radar antenna by using the relatively mature military phased array radar technology. Its purpose is to gather the electromagnetic wave into a narrow beam to transmit underground (or detection object) through the phased array technology, and receive the radar echo signal reflected by the target by using the multi-channel acquisition technology, The advanced data processing is carried out, and finally the three-dimensional image of the internal structure of the detection object is given.Development prospect of ground penetrating radar technologyIt is worth noting that at present, similar products have appeared in the market, such as RIS antenna array series of a company, but these products simply combine multiple monopole antennas into array antennas, which is essentially different from the idea of phased array ground penetrating radar.Because the phased array radar converges the electromagnetic wave into a narrow beam by controlling the phase delay of each channel, the energy is concentrated and the wave front diffusion is small. Therefore, the detection depth of the phased array radar is much larger under the condition of the same frequency and transmission power; On the contrary, under the same detection depth, phased array radar can improve the transmission power, so its resolution is much higher than the existing radar. In addition, since the spherical wave transmission is changed to beam transmission, the influence of medium heterogeneity is much smaller.Secondly, the phased array radar works in a continuous scanning mode and can scan in multiple directions. Therefore, the amount of information is much larger than that of the existing ground penetrating radar. For some special detection work, such as the quality detection of embankment cut-off wall, its role is unmatched by the existing ground penetrating radar (monopole antenna radar can not detect the joints, forks and other defects of embankment cut-off wall at all).Because phased array radar is a multi-channel received signal, multi-channel superposition can be carried out, just like the multiple coverage technology of reflection seismic exploration. Therefore, multiple interference can be greatly eliminated, which is difficult for existing radars. The antenna of high frequency (600mhz-1ghz) phased array ground penetrating radar can be made smaller, and its advantages are unmatched by the existing ground penetrating radar in shallow detection.At present, the system prototype has been completed. The carrier free pulse working system with center frequency of 900MHz is adopted, and the transmitting and receiving antennas are separated. 16 (4 × 4) Transmit channel forming, beam aggregation and scanning 16 (4) × 4) The channel receives the echo, and the optional scanning angles are - 36 °, - 24 °, - 12 °, 0 °, 12 °, 24 ° and 36 °.The software part of the system has rich data processing functions. The main conventional processing includes filtering, gain adjustment, static and dynamic correction, deconvolution, complex signal analysis, time-frequency analysis, etc., and multi-channel data processing, such as velocity analysis, superposition technology, coherence analysis technology, array signal processing, etc. And weak signal extraction, target automatic recognition and inversion interpretation under various clutter interference. A large number of field experiments on concrete detection in Yichang Three Gorges dam are carried out. The experimental results show that the spotlight scanning function of phased array radar has been realized, the penetration depth is greater than 1.5m and the resolution is higher than that of ordinary radar.Editing: hfy

So I am thinking of a possible answer to my own question:Build my own journal note entry app linked to a wiki.Zim Wiki uses a file based system for wiki. Maybe I could write app to export/sync entries in its files. Or WikkaWikki uses a MySQL (which is probably what I would use for journal entries anyway) so perhaps use same DB for Wiki and journal, with Journal app "doing right thing" to enter/sync Entries in wiki.Does this seem like a good approach?Or maybe I can customize a wiki with existing plugins - "All" I really need is good journaling / date feature, time tracking, checklist, and tags. Perhaps there already are plugins for this?Please comment if you have feedback on this idea.1. Circular tag wiki excerptsTag excerpts should at least try and give a concise definition as to the subject, and provided any usage guidance if necessary.Therefore, you need to make sure to address a set of key points:In general, excerpts should provide at least some guidance, even if it may appear to be ridiculously basic. Therefore, interpretation of the rejection reason is critical:That's like saying, [abs]: For questions about [abs] filaments. That should probably be rejected. This is better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use.Or even better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use. Not to be confused with [pla] filaments. Do not use this tag if your question does not concern this filament specifically. Obviously, I have no idea if abs is even a thing. Anyways, I hope this helps :)2. Why is this answer a community wiki?Apparently the answer under scrutiny was made CW because it drew on an answer from another Stack site, and the answerer wanted to share it without being associated with it for good or for ill.But community wiki is not a tool for reputation denial (or for dodging the repercussions of questionable-quality answers) and practically speaking I see no difference between quoting a different Stack and quoting a blog or a book. We would never expect someone to eschew rep for quoting a blog or a book. The answerer went to the trouble of tracking down the information and sharing it; why should not rep gains should reflect that?The moderation team is under no obligation to revert the CW in this case, nor are they obligated to leave it be, but I would lean toward reverting it myself, for reasons which follow.We've talked about posting answers from other sites, and it's pretty clear this is not cheese.Community wiki used to be massively overused. Changes to the editing system rendered its original purpose largely moot, and there's now a lot of confusion about CW's role in the Stack mechanics. These days there are three basic reasons to use CW:I do not see this particular answer needing CW to make it "easier to edit and maintain by a wider group of users," so I do not see any reason for it to be a community wiki. Community wiki is a tool with a specific set of uses, and CW rollbacks are left to mod discretion. One of the responsibilities of our moderators is to help the community use the right tools for the job at hand.As for the answer itself--it's not very good by lit.se standards, because it was written for a different site with different priorities. And the question itself is under a tag whose implementation is still being debated, so quality there is... in flux, I suppose we could say. We need to bring in our own expertise and tailor the answer to meet the expectations of our own Stack.3. Need to Change Edit Approval Limits for Tag Wiki EditorsI just upped it from 3 to 5. Hopefully this alleviates the issue a bit. If we still notice a pattern of users being blocked we can look at adjusting further4. Difference between Wiki Library and Document LibraryYes there is difference, Below might be helpful to understand.Document library can contains documents, it can be any document like office documetnts doc,xls,ppt, js, css, jpg, png etc...any file extension you can think of. Main purpose of document library is to store documents. wiki library is a kind of document library which contains wiki pages, Wiki pages are html pages with rich text editing capabilities so that users can create pages using Rich Text Editor without knowing html in detail. So when wiki library template is selected it comes with some default columns created based on content type, this columns are useful to create wiki page. Making changes and edits in a wiki page is incredibly easy. Just click on the edit button (at the top of the page) and immediately the page appears as an editor's version of the page. You can then make edits straight away and simply hit save. The page will instantly be up and running with your changes in place.

They do not want one so they do not have one. Frankly, the national championship playoff debate is a joke. This is something created by sportswriters and tolkshow hosts for the sole benefit of sportswriters and talkshow hosts. The NCAA does not recognize a national champion of the FBS so any discussion about who should or should not be the champion is pointless bloviating. Win your conference. Beat your rivals. Go to a bowl game. Those are the only things that matter in college football.8. What was determining the NCAA football title like in pre-BCS years?Hawaii, is not a very reliable team, yet might desire to win the Sugar Bowl in simple terms as surely as Georgia as a results of fact their offense constantly performs like its at the back of and it wears down the protection whilst they might desire to conceal the whole field. The unfold offense is the excellent offense in college soccer. It supplies much less gifted communities liek Hawaii and Illinois a gamble to beat far extra gifted communities. that's alsovery risky, that's why some exceptionally ranked communities dont run it. Hawaii surely did no longer deserve a identify shot in simple terms as a results of fact Boise State gained The Fiesta Bowl. Boise beat a BCS convention team who complete 10-4(Oregon State who beat USC and Hawaii in Hawaii) Hawaii has no high quality wins and does not deserve a NT shot. ending undefeated might desire to get you a BCS sport nevertheless9.
