Stata tables: Using esttab, indicate() with xtreg. Professor Schaffer, Thank you for your quick response. When I run the ivregress 2sls command, the instrument does ivreg2 also struggle when you don't partial out? I wouldn't be surprised if it does, but we rewrote the collinearity code for ivreg2 recently and it would be interesting to know . But if you have a panel, what you want is Mark Schaffer's xtivreg2, which is a 'wrapper' for ivreg2.

Stata’s cluster() Anyway, this command has the following syntax: newey y x, lag() The standard Newey-West procedure as implemented through newey does not allow for this, but the ivreg2 does because it estimates robust, AC and HAC standard errors for Stata操作. So (d1 d1_d2 = iv iv_d2) would be acceptable. I believe I can still use ivreg2 to deal with this problem.
