woolridge book says that R=ey(hat)y. That means ey(hat)y=exy?? why???

RSS/TSS

Thank you very much for this very detailed explanation. It helped a lot in my studies in Econometrics

You made something impossible look easy. thank you!

Incredibly helpful, thank you so much!

Top notch good sir!

i understand the math well enough to get the idea. im studying for a CMA/ management accountant) do i need to add more algebra to my education to be good at my new career?

thanks

why did we get Beta square when taking it out ? coz variance ( a X ) = A^2 variance ( X)

Great video. Cheers!

Thank you!

thank you so much

Thank you so much, bless you

this video literally carried me on one of the questions on my econometrics exam lol

why beta_0 is not a random variable?

Thanks

Thanks so much!!

Awesome explanation. But SSE=(yi-y_hat i)^2 and SSR=(y_hat I - y_bar)^2 and not the other way round.

Var of Beta not Hat possess var of Beta 1 hat .solve this problem plz?

Aoa can u Hepl me in one problem?

Thanks a lot !

Brother can you make a video on derivation of ARMA model, difference equation in time Series Econometrics derivation and it's solutions and numericals also,Ardl Bound test derivation and differential equation in time Series Econometrics derivation.

THANK YOU, I HOPE YOU HAVE A GREAT YEAR

thankyou!!

what was that first order business? I didn't understand that. How it is summing to zero?

R^2 = 1 - SSE/SST, not = SSE/SST

Thanks for this lecture. It was very helpful.

Very easily explained

Really good proof!

Very well explained! Thank you.

Does this proof hold for n = 1?

if sum of xi and xbar =0 whats the point of solving everything is zero then........................why care solve anything we can put everything zero as per convience. THIS SOLUTION IS JUST A LIE LOL

man thank god for all the guys like you out here

Thanks for this! It really helped

i still don't get it, can please you explain why Ui hat times Yi hat equal to zero? Thanks

Crazy video, but I am still confused after watching this...

Hi, I have an econometric question, is there a way for me to ask it to you ? Thanks !

thanks!

Explanation is too fast and not clear

Did not understand why (xi -x bar) is not conditional on x... Please help

Easynomics>my lecturer🚶‍♂️

Damn! You're a lifesaver. You decomposed everything to my understanding. Thanks🙏

Thanks for the nice video! One Question Sir, your first equality, does Var(y-y_hat) =?= Var(y) - Var(y_hat) ? y and y_hat independent?

pleas help me

thank you so much, becuase of you I was able to do my homeworkd

what about the multiple linear regression??

Thanks

Thanks!

Can someone explain me where I went wrong here: If we know that ESS = 0, doesn't that imply that RSS/TSS = 1? And that implies that RSS can not be equal to zero. And the formula for RSS = Sum(Yi - Yi-bar)^2 then Yi can't be equal to Yi-bar. However with the formula for Beta^1 being Beta^1 = Cov(X,Y)/Var(X), and Cov= Sum(Xi - Xi-bar) * (Yi - Yi-bar). And we know that Yi - Yi-bar can not be equal to zero, then under the assumption that Var(X) = 0, the cov(x,y) can not be equal to zero and with that Beta^1 can not be zero either.

THANK YOU SO MUCH YOU HELPED ME WITH MY PROBLEM SET:)) WISH YOU THE BEST
