Hi,

Thank you for the suggestion. Specifically, I am intended to run the Lagrange multiplier (efficient score) approach (recommended by Lung-fei Lee 2001) for -heckman- specification checking. I am using the STATA v.8.2. Would you please suggest an equivalent command realize a similar function, or diagnostic test statistics for detecting the heckman model misspecification.

Best Regards,

Dear Statalists,

Following the standard procedure of score estimation after -probit- and -heckman-, I constantly got the following error with -testomit- command.

unrecognized command: enumopt
r(199);

Would anyone please recommend a solution?

Best Regards,
Yang

If you do -findit enumopt- you will see that there is a program by that name also written by the author of -testomit-, Jeroen Weesie. Of course whether it is the right program is another question! I would suggest emailing the author.

Also, what version of Stata are you using? Some post-estimation commands need to be rewritten for Stata 9, or else you need to use version control, e.g. something like

version 8.2: probit y x
testomit...
