mm_sample() from -moremata- is required; type ssc install moremata
r(499);
end of do-file
r(499);

Yet I do have moremata. I checked:

. ssc install moremata
checking moremata consistency and verifying not already installed...
all files already exist and are up to date.
.

Has anybody seen this kind of phantom ssc installs before? How did you
fix yours?


After you install a SSC package containing a Mata object library, you must reindex the list of Mata libraries before the library from the newly-installed package becomes available. Do this by:

(1) quit Stata and start it again, which will create the proper index, or

(2) issue command

mata: mata mlib index

which will do it during the current Stata session.
