please, vedio is not clearly visible
Woww thank you sir
My advice is to either do your GCSE through college or just do IELTS Academic Test in one of the exam centres where there is more oversight. These people have no incentives to pass you, especially since you can come back as a returning customer for a resit. Take caution!
After deleting the outliers the validity of results significantly dropped by more than 8%, is it okay?
Thnks 🎉
This was exactly what I was looking for and you explained it very easily to understand. Thank you!
Thanks for your efforts
Try timestamps, dude!
🙏🙏🙏🙏🙏
Thank you so much it is constructive.I appreciate your help
Thanks so much !
Aoa sir have you any idea about writing topic please guide me ... I book my test 6 june.
It can be any topic. Like either writing essay, article in a newspaper, letter, or application. Some sample writings I practiced during my exam prep have shared in the link. Wish you best.
Sir you may send the source A and B for the relevant solved past papers.
@@sadiahaleema3386 these sources are in AQA GCSE English paper 1 and 2. Year is already mentioned in each solution. i guess you can download them from internet.
Ok sir thank you.
How was your exam? Mine is next week. If you share some ideas, it would be helpful
Assalamualaikum Sir kindly share past paper
As a sample plz send source A and B that relevant to your solved past paer
thank u helps a lot!
I am preparing for this exam now, and the total is currently 55 marks to pass.
wish you all the best. When I appeared the score was graded on 9-4 scale i guess and 4 was a pass.
Hello
Can you guide me plz today i book my eng test
Hello
@@nudratanees5851 What do you want to know exactly?
Hi, I have 4 dependent variables, when I run the hausman test for each one of them, 2 of them validate the random effect model, and the 2 others validate the fe model. Now which one to choose since I'm doing a multivariate regression? And on top of that, some of my dummy variables (useful ones) are omitted omitted under fixed effect, but I really need to use them.
This is insane, you didn’t do panel violation diagnostic tests, what you just did is only time series violation assumptions, whatch out your title please, it’s totally different panel and time series
Hey, go and do whatever you think is right. Or make a video and post of what you think is right. Who stops you. I did what I understood during my research and tried to help people. Cheers.
@@dr.rahman107you are misleading people here, you just conducted a Pooled OLS disregarding any cross sectional variation (which is the main motive of panel data study). It would be better if you changed your title to Pooled OLS diagnostic test in panel dataset. Nonetheless, thankyou for presenting a detailed diagnostic analysis of Pooled OLS
@@dr.rahman107all those tests are informative as data have such a problems in the beginning and we have to deal with problematic data and post analysis is only possible solution (after ols), a lot of people do not understand the logic of initial testing in order to choose right estimator. thanks for video
Hello Dr.Rahman, Thank very much you for this video. It is very helpful. As I can see in the MS Word document, the Sources texts A and B for each question do not appear, is there any way to have them? and are the sources A and B four all the 5 questions or each questions has its own two sources A and B ?
If you could provide me with the link from where I can download the papers, from the AQA website, because when I searched on the site via keywords I did not find them.
Hi thanks for your comments. You should consult the past papers of GCSE mentioned there for reference texts
@@dr.rahman107 Unfortunately, I did not find the version of the sources you worked on, I would like to have them to compare your answers to mine. as you it is very complicated to practice on questions without the sources. I will be very grateful if you could share with me the sources you worked on ? Thank you very much
Hello. These are AQA GCSE English language paper. Year is written in my answers. These are available on internet. Every year there are two exams. Please help yourself.
@@theinterpreterghas these are AQA papers and year is mentioned with each answer. these papers are conducted twice in a year, so spring or fall. both mentioned in my practice attempts.
Very informative video! Could you make similar A star equivalency test videos for maths and science as well??
Hahaha. I did this test myself so, when I was preparing thought to make a video for other people’s help and put up all my practice material there online. But I don’t need to take maths and science, so, let’s hope someone who prepares for these tests helps others by making a video.😀
I have seen AQA gcse past papers it has English literature like Macbeth, Romeo & juliet etc. Do I need to study literature too? Is this part of A star equivalency test ? Thanks
You have to pass English language not literature. So only focus on English language paper 1 and 2. The guidelines and questions numbers in aqa GCSE papers given in these guidelines are perfect. Follow it . It will be all right.
hi. It's possibile add the time effects to fe regression?
Thank you for the video. Where is the 2.68 value you mentioned come from?
Thanks for watching the video. Z score of 2.68 is considered to be within 99% of the normal distribution of a bell curve. Therefore, its suggested as a cut off point. You can further check its details from internet.
Thank you very much😊
Do you know if the actual exam is similar to those given in the sample papers? Also, does the word count for the indicative content fulfil the AOs?
AOs already given in ppt. And the time is too short, so can't write long answers. The guidelines given are fine. And actual paper was also similar to what has been explained here. Follow given guidelines for length of answer, it should be fine.
Please I want to ask you about the non fiction writing part.. is it just about a letter or article only? Or it could include other types like speech??
It would be an essay form where you have to express your ideas in paragraph form. Most likely a letter of article.
Thank you for the video. Can I draw the amos by hand? Amos created result is very unclear and I cant read properly many numbers
Do not think so. Reviewers and journals won't accept hand drawn sketch, due to reliability of result issues. Software generated diagrams give credibility to the process.
Brother Rahman - is this test online? can a person get help from google during test?
Yes online, but help in anyway is not allowed.
thanks brother for your prompt reply - is computer's screen shared during test? @@dr.rahman107
Thank you sir for your insightful lessons, i want check for heteroskedasticity but i go this error "estat hettest not valid r(321); " pls pus some light on it.
5:13 correlation: significance level 0.05 or less then star marks
Thank you very much, it is very useful for those like me who have not been exposed to GCSE equivalency tests before!
welcome. One additional advise. Attempt practice papers by keeping the time. Time management is going to be the most crucial thing which will decide the result apart from your English.
did you give test? how was it?
@@muhammadumair9020 . Yeah, I passed. I could not manage my time well during the exam. yet, still, scored much higher than required.
Grateful!
very simple to understand. Well done!
I have arranged 54 conntry 2002 to 2020 5 veriable data set and try to import in eviews 12 while i select dated pannel and input year and coutry identifyer it gives error message that cross identyfier ir lets say countey id value is dublicated what should i do. Thanks in advance .
thanks a lot
Thank you Dr for the helpful video. I ma currently want to do a panel data regression for the companies in Europe. the name of the company and the country are not important for my regression so I might delete them. The regression will be during 7 years. so how should I create the ID variable? should I create it depending on the company name then delete the company name and leave the ID? Thank you.
Thank you very much for your comment. The ID variable makes the identity of the repeating variable distinguishable for the STATA to analyze. The repeating variable should be given ID, whether company or country. In my example, the country was given id, as the data for country repeats each year . In your case, if same company data repeats each year, the company should be given ID, so that software recognize this data repeats for same company every year. You can keep company name, but, do not include in your analysis. I think you do not need to delete it, even if you do not need it for analysis. I hope this answers your question.
How can we perform this with a panel containing more than 100 countries?
Thanks for your comment. For downloading, no issue, you can select as many countries as you want from WB data as in 1:50 second video you can see all countries options available. for making it panel in spreadsheet, however, you have to copy and paste for each country. so, may be if you have 100 countries, you have to perform copy paste for 100 times. While collecting data for research, i think you got to do this much of effort at least.
@@dr.rahman107 Many thanks for your reply. However, I found another tip that can allow me to perform the data collection as a Panel at once with the assistance of STATA: th-cam.com/video/tOcv505-zi4/w-d-xo.html&ab_channel=OdaaMargaa
@@dr.rahman107 before making a video you should learn how it works
Hello. Am I correct in saying you run these diagnostic tests on the simple OLS regression that has not fixed time and entity effects? Then, if the data passes all of the tests, you can go on to conduct the fixed effects regression?
goated
Thank you!
Thank you for the informative video. Could you please share how correct if the problems of heteroscedasticity, autocorrelation, multicollinearity are found in panel data
thanks for the question. If I understood your question correctly. if the significance level of these tests is greater than 0.05, then there is no problems. If you find these tests significant(smaller than 0.05), your data has these issues, and hence, your results will be biased. Hope it answers the question.
@anjalitandon4047 maam can you share any link from where you get solution of these problems? as If you these tests significant(smaller than 0.05), is only indicator .. not the solution....
Well Educative video indeed. Keep it up.
thank you for the video, it's very helpfull. i struggled finding this kind of video on youtube, I found it through google
Can we do this Postestimation tests for xtreg commands because i need to run the tests on my fixed effects regression
Hi, Thanks for the question. all tests not possible with xtreg. If you go to the post estimation tab, you can find that some of the tests only possible with time series setting. So, for that you have to change your data to time series if you need those tests, such as Breuch-Godfrey test. Others you can do with xtreg or the panel data setting.
@@dr.rahman107 thank you for answering fast and precise. how do i find out if i need postestimation Tests for my paneldata or Not? Its Hard to find a source with a holistic explanation for my analysis
@@damir2go . You should do post estimation tests to prove that your data and results does not suffer from any biases. However, which all tests is subjective. Some do both tests related to time series and panel even if your hypothesis testing is only based on panel set up. Better you can read research papers in your field and in journal where you are aiming to publish. that can give you a hint about what all post estimation tests you should conduct.
Thank you very much! This video is very useful, I've been looking for this information for a long time....
