Hi all,

I tried to fix the problem I have with the following syntax:

mi xeq 1/`M': regress problemuse_CIDI_OH audcscore iatalcohol satalcohol; scalar r2 = r2 + e(r2)

When I do it on STATA, it says invalid numlist r(121);

Could you help me to figure out what is the mistake?

Thank you very much,

Angeline
