Hi,

I am trying to run a multivariate tobit model using lots of dummy independent variables for my undergraduate dissertation. The mvtobit help file says "A limitation is that only models left ccensored at zero can be estimated". Is this to say that right censoring is not possible at all? My dependent variables are right censored. I have tried to use the cmp command as an alternative but it fails to converge the full model, returning hundreds of "logpseudoliklihood=0 (not concave) iterations. I believe this is due to multicollinearity. Is there a way to address this? Many thanks,

Jake
