st: Tobit in Stata vs. Limdep

[frone@ria.buffalo.edu]

I've run a tobit analysis using Stata and Limdep.  However, the 
coefficients (and z-tests) are quite different.  Has any one done such a 
comparison and can shed light on why this might happen?  Just as a 
secondary check, I dichotomized the outcome and ran a probit in both 
programs and obtained Identical results.
