Understanding Heteroskedasticity

[@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!!! 

Thank you so much you have been making my journey in econometrics easier. I know you meant 18 letters and not 18 words. Good job prof.

[@CrunchEconometrix]

Hahahaha thanks, Esther. Yeah meant letters. Funny I didn't realize I said that until you pointed it out 🙏😊

thank you CrunchEconometrics for video. please upload the video about autocorrelation also. im waiting for that too.

[@CrunchEconometrix]

U're welcome, Naw. I'll do my best to upload your suggestion once I have all information. Thanks a lot!

Hello, please How do I perform the Breush Pagan LM cross sectional dependency in STATA? Thank you

[@CrunchEconometrix]

I don't have a specific video on this. So, you can resort to Stata HELP Menu for detailed guidance.

@@CrunchEconometrix Hey prof , i've Just encountered an intricacy and would like to here what you think about It. I estimated a Linear model where human capital had no role in promoting growth. But when interacted with another macroeconomic variable, the interaction variable is positive and significant. However, human capital becomes negative. So my worry is, Is It normal for human capital to have a negative and significant impact on growth in the presence of the interaction variable? What Can be a plausible interpretation ?

[@CrunchEconometrix]

@@asanteka.2403 Such findings are common with studies on SSA countries due to the poor development of the labour force becomes a drag on growth.

[@asanteka.2403]

@@CrunchEconometrix thanks very much prof, you are Just wonderful Best wishes for this year and we'll be waiting for many more Lectures for thé upcoming 2020.

[@fadijasmin1]

Thank you for this appreciated explanation. . But I have a question related to the inefficient estimate caused by such problem. In fact an inefficient estimate, as you say, means that this estimate does not have the minimum variance, so that it has a big variance and hence a big standard error?? Consequently a smaller t or F statistic than it should be?? So here an error of type II

[@CrunchEconometrix]

Hi Matar, thanks for the feedback but you are mixing things up. Heteroskedasticity implies that the variance is not constant which can be increasing or decreasing. Het UNDERESTIMATES the SE which is the sqrt of the variance. I will encourage you to consult further references indicated at the end of the video. Please may I know from where (location) you are reaching me? Thanks.

[@fadijasmin1]

Thank you sincerely for your reply I will do a quick revision of the cited references to clarify this idea I reach you from Syria and always wish you the best a+

[@CrunchEconometrix]

@@fadijasmin1 No worries 😊. I'll appreciate it if you can share the link to my KZbin Channel with your friends and academic community in Syria 🇸🇾. They will find the content helpful too 😊.
