Question
(Extra problem) Let Ybi be the fitted value of Yi from fitting the simple linear regression model. Show that b(Yi , Ybi) = |b(Yi ,
(Extra problem) Let Ybi be the fitted value of Yi from fitting the simple linear regression model. Show that b(Yi
, Ybi) = |b(Yi
, Xi)|. That is, the sample correlation coefficient of
{(Yi , Ybi)} n i=1 must be positive, and is equivalent to the absolute value of the sample correlation coefficient of {(Yi , Xi)} n i=1.
