[@modounjie3334]

Never once have I ever understood an explanation as clearer as this one. Thank you, sir. You are definitely great.

[@keshavkumar5331]

Very good explanation. Thank you sir 🎉

Hello could do u pls mk a video on the lack of fit test🙂

[@muhammadsaqib3655]

you explained it very well............thank you

[@chinesecultureinessence1534]

best video so far for regression. Why my text book is k-2 instead of k-1? degree of freedom always makes me baffled.

What is the definition and how to calculate the standard error of b1? (Simply given as 0.19 here)

Please watch the following video from around minute 6:30: kzbin.info/www/bejne/oqLIoJaVpraqnrM

Can't we use the degrees of freedom = number of observations "n" - 1 not "n" - K?

[@PatObi]

n-1 is total DF. But DF for regression is n-k, where k = number of parameters including the intercept.

@@PatObi so if I'm trying to get degrees of freedom for T-Test, it should be n-p, right? where p = k+1?
