Stata version error for weakiv

[Grace Cai Lee]

Dear all

I am using Stata 17.0 to run the official example of weakiv.

Here are the commands:

clear
use http://www.stata.com/data/jwooldridge/eacsap/mroz.dta
weakiv ivreg2 lwage (educ exper = fatheduc motheduc kidslt6 kidsge6), robust gridpoints(30 30) graph(k) project(_all)

But I got the error saying, "WARNING: Tested only for Stata version 15.1 and higher. Your Stata version 11.2 is not officially supported."

Could anyone give me some advice on this problem? Thank you in advance.

The warning seems to be produced by surface.ado, which is being called by weakiv.ado, because weakiv sets the version to 11.2.

I am not sure if this is causing any actual problem; the code seems to work with the dataset you specify, and does not give any error, only the warning. Perhaps just ignore it?

Thanks a lot for your reply, Hemanshu! Your information is relieving. I think I can ignore the warning for now. Thanks again!
