(Stata16): Heteroskedasticity and Weighted (Generalised) Least Squares

[@CrunchEconometrix]

I want to appreciate all my subscribers from across the globe (Africa, Asia, Europe, the Middle East, The Americas, and The Pacific). Thank you all for your support. I am encouraged by your comments, questions, likes and critiques. They keep me focussed and poised to do better. I will continue to contribute my little quota such that every student and researcher will independently analyse his/her data. My teaching approach is very practical. I adopt a do-as-I-do style. Many thanks to those who have supported me by telling others. Once again, CrunchEconometrix loves to teach, support my Channel with your subscription, likes, feedbacks and sharing my videos with your cohorts. Please do not keep me to yourself (lol) inform your friends, students and academic networks about my Channel. Tell them CrunchEconometrix breaks down the econometric jargons and teaches with simplicity. Follow me on Facebook, Twitter and Reddit. Love you all, greatly!!! 

I struggled with this subject along the semester and founding this video just left everything clear in 10 minutes. Thanks for taking the time to upload it!!!

[@CrunchEconometrix]

Great to hear, Emiliano!

Thanks for this Ma. I want to understand something. Changing the variables into a log form to correct Heteroskedasticity is that what GLS is all about? I understood the correction of Heteroskedasticity using the functional form as you taught. This particular one does it mean that when you change the cariables to a log form and you run the regression again, then check for heteroskedasticity, it is corrected and thus meaning GLS?

Hi Kezia, thanks for the positive feedback. The video description says it all. Answers your query.

@CrunchEconometrix, Thank you maa'm....it helpedme a lot

[@CrunchEconometrix]

Glad to hear, Ismat😊

Hello once again, can you please how to add the weight variable? Because if I am simply putting (weight/1/myIV) then Stata is giving an error. Can you please elaborate? I would be highly grateful. Thanks in advance.

Hi Fawa, why not follow the steps shown?

[@ahyz5759]

Hi, Is there any rule to select the Z known variable, independent variable? Or i can choose it randomly?

[@CrunchEconometrix]

Hi, kindly watch the clip again. Thanks.

@crunchEconometrix In correcting for heteroskedasticity in RE model ... which is the best estimator ? Robustness of RE or FGLS

[@CrunchEconometrix]

Hi Kingsley, either approach works well insofar the heteroskedasticity is eliminated.

[@kingsleygyan810]

@@CrunchEconometrix thanks soo much

[@fahimmukhtar8349]

teacher how it is known that sqfeet is causing heteroscedasticity?

[@CrunchEconometrix]

Hi Fahim, I explained how to detect heteroscedasticity so kindly watch the videos again.
