Thanks for the help!
Does this type of linear model work if X1 and X2 are categorical variables?

Hi William.
You should be able to fit this kind of model using gls in the nlme
package. In your case,
Quick correction: index variables are transformed into n x (k - 1) matrices
of INDICATOR variables.

Hi Will,
Quick answer to that question: yes.
The key is that categorical variables cannot be modeled directly in a GLM
Excellent, thanks Peter!
