Excellent video. I graduated with a BA Econ. and MBA Intl. Econ. Econometrics was not taught much then, rather they used standard Statistics instead. I found that to be wanting and disappointing in not being able to perform primary research and modeling based on real economic data. If we want, (and we do need) to build meaningful Economic models we need to use meaningful and applicable data to prove our hypotheses: enter the required need for Econometrics.
17:11 if U is always equal to 0 (zero conditional mean) then how is it possible that U changes when X changes, U=0 hence there should be nothing since 0 =0, you will get the linear line only then right. anyone has the answer?
U is not equals to 0, but expected value of u is 0. That means, u might have a distribution, but in such a way that mean comes out to be 0. Hope you understood.
Econometrics as a subject needs more great videos like this badly. Like most fields of statistics, it tends to be taught very poorly
Thank you so much for this amazing series. I am gaining tremendously from your lectures as a PhD scholar from a different background.

Thank you for the amazing lesson. Truly aprecciate it
Very good resource. Thanks a lot
great lesson.
Great videos, thank you very much!!!
sir do Y comes from normal distribution?
Thankyou so much sir
thank youuu!!!
why is there an extra xi
where
Thanks
Zee Germans...😂 Thank you for the presentations
