Hi, 

I have just installed the Baum-Schaffer-Stillman
version of ivreg2 using "findit ivreg2" in stata, but
the fwl option is not working anymore. I am getting an
error: "option fwl() not allowed"

The same code worked just fine with the old version.
Is there a problem with the fwl in the new ivreg2
version? 

Thanks, 
aslihan
