I am using ivtobit. However, stata does not show the first stage outcome when using the vce(bootstrap,reps(50)) option.
Code:
webuse laborsup ivtobit fem_inc fem_educ kids (other_inc = male_educ), ll(12) vce(bootstrap,reps(50)) first twostep
Code:
. ivtobit fem_inc fem_educ kids (other_inc = male_educ), ll(12) vce(bootstrap,reps(50)) first twostep (running ivtobit on estimation sample) Bootstrap replications (50) ----+--- 1 ---+--- 2 ---+--- 3 ---+--- 4 ---+--- 5 .................................................. 50 Two-step tobit with endogenous regressors Number of obs = 500 Uncensored = 211 Limits: lower = 12 Left-censored = 289 upper = +inf Right-censored = 0 Wald chi2(3) = 111.52 Prob > chi2 = 0.0000 ------------------------------------------------------------------------------ | Observed Bootstrap Normal-based | Coef.
