Hi there

SAS users tell me that PROC GLM allows analysis of a factorial design that
includes a continuous variable as an IV. Previously, I was running
Regression so as not to perform a dichotomous split on my continuous
variable. I have an old version of SPSS, which does not have GLM.

Having been given this advice, I ran my data using SPSS's GLM function
(repeated measures) and discovered that it is treating the continuous
variable as categorical. I think that is what is happening because this
variable is eating up 21 degrees of freedom. As a result I have lost some
findings I obtained using the regression.

Is there any way around this or will I need to revert back to using
regression? Sorry this seems like a stupid question.

Thanks in advance.
