Oct 25, 2019 at 10:41 comment added carlo this is a little misleading because the red area of the second graph doesn't really represent anything in multiple regression (what is the middle region instead?)

Aug 14, 2019 at 13:43 comment added damai Thanks. If age will indeed affect GPA, then age is actually included in the error term in the regression function of GPA on IQ, right? Similarly, IQ is included in the error term in the regression function of GPA on age. Then, we are actually doing two multiple regressions not simple regressions? I'm confused.
