Hi, I have a pentium III 600 with 128 ram running Linux.
I try this and fail. Memory problem.

You know so? My calculations made this a 1.9Gb design matrix with more columns than rows, so (a) my guess is that you will hit the 4Gb/process address limit in i686 Linux and (b) it won't `work' in any statistically meaningful way. That model fits all products of 0 to 4 continuous variables in each cell of a 22*14*4 (from memory) contingency table. I think it is the statistical strategy that needs to be thought through.
