Re: Linearity of Independent varialbles in Multiple Regression.

By linearity i meant whether there is linear relationship between the
independent variables and the dependent variable or not or do we need
independent variables in quadratic or some other non-linear form. Also
I mentioned box cox transformation because there is such procedure in
SAS which suggests transformation for the dependent variable.
Thanks

Take a look at the book by Aiken & West, if your library has it.
