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!

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.

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.
@dr.rahman107
@dr.rahman107 Жыл бұрын
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.

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.

@@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.
