Hello
I am using Stata 12.0 and I am attempting to run a fractional probit
regression with the command: glm dependent independent, fa(bin)
link(probit) cluster(gck). I have made sure that the dependent
variable values are not negative. I have 1500 dependent variable
observations out of 69,900 that fall at 0 and 1. Regardless of whether
I leave in the 0 and 1 values or take them out, I get the same log
likelihood iteration followed by backed up. It continues like this and
does not converge until I break it.
Has anyone else had this problem and know a solution to it? I do have
several variables but they are all necessary to my regression. I have
also tried the difficult option but that does not work either.
