Dear all, I am trying to use the Clarify for my two separate models (one with the zinb model and the other with the mlogit model). First, it looks like the program does not support either the zip or zinb model; what are some alternatives other than using the nbreg or poisson model? Second, for my mlogit analysis, it looks like the program does not support the cluster option (the error message �matrix not positive definite�); what are some alternatives? Thanks so much in advance. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
