Reading for January 8
Fragment of a discussion from Course talk:STAT 550 2013
(Paper 1) What are the detailed steps to do the multiple regression to find whether subjects with a high value of X tend also to have a high value of Y?
(Paper 2) The slope is less than 1 if we switch X and Y, the height of parents and that of childs, given that they have the same mean and variance. Of course, the slope is still less than 1 when we don't switch them. Does this contradict the notion of "regression toward mediocrity"?
(Paper 4) The author already stated that ANCOVA generally has greater statistical power. Then why don't we just use ANCOVA even when there is a high correlation?
