st: estimate of rho in tobit

["Lijiang Shen" <lshen@uga.edu>]

Dear All,

I am new to Stata and I have a question about tobit analysis in Stata. The 
tobit procedure yields estimates of sigma and coefficients for each 
predictors, among others. My question is, how do I get the estimate of rho 
(the correlation between the error terms in the outcome model and the 
selection model)?

thanks!
