I'm no matrix expert, but there is a logical problem here. You define x and y as variables and they can take on a different value for each observation (although you are giving them the same value for each observation in your example). so it is unclear which values of x and y your matrix command would use. . display x Gives you the value of x in the first observation (although it is unclear to me why Stata lets you do this). Perhaps what you need are local macros? . local x 1 . local y 1 . matrix byvar = (`x',`y') Daniel No virus found in this outgoing message. Checked by AVG Free Edition.
