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.
