Because the interaction term is insignificant, I should say A has the same effect in B=0 vs B=1? Close, but not quite; you should say that you cannot reject the hypothesis that the effects are the same. Remember, with statistical tests you can never confirm a hypothesis, you can only reject or fail to reject. The latter is not the same as accepting. In essence failing to reject means that there is "absence of evidence" and this is not the same as "evidence of absence". -- Maarten --------------------------------- Maarten L.
