  • Adjusted R-Squared for XTIVREG FE Model

    I have ran the following 2SLS fixed effect regression using --xtivreg-- however, the command with --fe-- do not produce ---adjusted r-squared--- as I have read through the documentation of the command. While looking into several other posts in the forum on the issue I have found some says to calculate manually while in another post shows that running the same regression with --regress-- might output equivalent adjusted r-sqaured from --xtreg-- (please note the forum member here talks about --xtreg-- command for re model --- this is just my interpretation for the sake of explaining my question)

    Is there is any way I could derive the adjusted-r-squared in this case or I could also imply the r-adjusted squared from the regress command might be equal to the xtivreg--fe-- command ?

    Thank you for your input.
