Dear Forum Members,
I am using multiply imputed data on Stata 15 and was wondering if anyone has any advice on how to get the first stage results for the two instrumental variables models I use:
1. The continuous outcome is maths exam: mi estimate, cmdok: ivreg2 maths (zbmi11 = stdscoresum) if sex==0, robust first

Here, the Stata output does not report any first stage regressions or tests of endogeneity, it only reports final results.2. My binary outcome is graduation: mi estimate, cmdok: ivprobit unigrad (zbmi17 = stdscoresum) if sex==1, robust first
Here, the Stata output reports the first stage regression but not any of the endogeneity checks (attached picture of output).Thank you for any assistance!
