Sorry, not as nice as it could be: there was a bug which biased the fitted value towards prediction of the base case. This is now fixed in CVS and the gretl snapshots for Windows and OS X. Thanks for directing our attention to this area. To make amends for this error ;-) I have now added an accessor $mnlprobs. After estimation of a multinomial logit model this gets a matrix of the outcome probabilities (rows = observations, columns = outcomes). logit ... --multinomial matrix P = $mnlprobs If you prefer, the columns can be extracted as series, as in series P2 = $mnlprobs[,2] No doubt this will get added to a GUI menu at some point, but right now it's a command-line thing only.
