I had nothing to do with the design, but it seems to make sense: For a binary probit, giving the prob p_1 of the case 1 tells you everything, because logically the other case must have 1-p_1. But with an ordered probit you need at least two probs, and you cannot fit this information into a single series. Ok you could say for consistency the binary probit then also should give just the predicted 0 and 1 after fcast. Have you tried looking what's in the $fcast accessor? Maybe somebody buried an easter egg in there for ordered probits. good luck, sven _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
