Hello 

Has anybody noticed that in treatreg, when using interactions of the
treatment with variables in the outcome equation, the postestimation predict
command that conditions on treatment (or non-treatment), does not condition
the interaction terms on treatment (or non-treatment)? It considers the
interaction terms just like any other variable, ignoring the fact that they
are interactions with the treatment. Does anybody know of any way to make
stata recognize them as interactions with the treatment so as to calculate
the correct predicted values?

Thanks
