This video directly follows part 1 in the StatQuest series on General Linear Models (GLMs) on Linear Regression https://www.youtube.com/watch?v=nk2CQITm_eo . This StatQuest shows how the exact same principles from "simple" linear regression also apply multiple regression. At the end, I show how to test if a multiple regression is better than a simple regression. To see how to do multiple regression in R, check out https://www.youtube.com/watch?v=hokALdIst8k For a complete index of all the StatQuest videos, check out: https://statquest.org/video-index/ If you'd like to support StatQuest, please consider...

The numerator should be: (SS(mean) - SS(fit))/(pfit - pmean) #statquest #regression
