F-tests and t-tests for multiple regression

[@Mahlodi_Makobe]

what a clear concise explanation. You have just saved my semester! thank you

[@echoleexn]

very clear. Thank you!

[@ccwnoob4393]

1:37 actually, it does not mean at least one "is useful"; it means at least one is not useless. big diff.

[@Maceta444]

Quite literally a life saver. Thank you so much!

[@raghu_yadav_yt]

Well explained. Very helpful video. 👍

[@mm.f262]

This was so helpful..Love you!

[@olivenethomas4042]

Wow! A million thanks for this!

[@pramesajuan329]

thank you for clearly explanation 👍 what software do you use to calculate the p-value

[@BillyHadinata]

how do you find each standard error manually?

[@abdulrahmanabunabhan4919]

very helpful video . is there a formula for calculating the standard error (SE) for the coefficient that we are performing the t test on? or will it usually be given to us?

[@catherinecase1142]

There are formulas, and they can be useful for understanding the various factors that affect standard error, but I wouldn’t try to do the calculations by hand. You’re already using software to find the slope, standard deviation of the residuals, etc. so you might as well take advantage of software in calculating the standard error of the coefficient too. (Of course, if this is for a statistics class, you should ask your teacher!)

thank you

aoa mam plz solve my problem i will be very thankful for it it i m from Pakistan actually my task is related to glr testing in which i have to prove beta and beta not and testing after this can u help mn this

[@moeski8556]

for the t test do we reject the null if it is significant

[@catherinecase1142]

Yes, it’s like other hypothesis tests in that way. Saying that a result is “significant” means we have strong evidence to reject the null.
