You are trying to use -ivreg2- (SSC) and -ranktest- (SSC). Please remember to explain where user-written commands you refer to come from. Also the heading -ivreg- is misleading as -ivreg- is a quite different command. Your problem is one with the associated Mata code. Please check that you downloaded the latest version of the Mata library required. --ssc desc ivreg2- and -ssc desc ranktest- show that you need to install livreg2.mlib. Sometimes closing and restarting Stata fixes small problems like this.

I am currently using stata 12.0 and the problem is that when I run the code on from a do file stata gives me a r(3000) error message and informs me that "struct ms_vcvorthog undefined", under the subheading "LIML" of the code. > > I would appreciate thoughts on what could be causing this problem and suggestions on how one could go about resolving it? > * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
