Dear colleagues,
I think that I read or heard somewhere, that in a multiple regression
procedure, the absence of effects of some variables may be due to the
strong effect of a few selected variables that "masks" the effects of
other variables.
Did you read or heard something like that or it is just a dream?
If you read it, references would be appreciated,
thanks
