Dear Statalisters, I have a GLM regression of the form: glm outcome var1 var2 i.var3 i.var4, link(log) fam(gamma) eform where the factor variable 'var4' has 20 levels.

Many thanks, Sam. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
