Hi, I am just wondering if there already exists a built-in accessors for the number of cases correctly predicted after a logit/probit estimation? I couldn't find any in the manual, but maybe I missed something. Best, Artur

I haven't yet worked with these models in gretl, but assuming that $yhat produces something useful there (like the probability), it should be pretty easy, no?: numcorrectpredict = sum(($yhat>0.5)==binarydep) hth, sven

I always forget about these nice if conditions within a function like "sum". Thank you for the example, Sven. Best, Artur Am 23.08.2013 13:02, schrieb Sven Schreiber:
