Hi,

I am trying to get a table of my first stage using ivreg2 and esttab. I would like to add the overidentification test statistic as well as the F statistic for the excluded instruments to the table. I have tried to do it using the "scalars"-option in esttab and calling on "j" and "widstat". It adds a row for both j and widstat, but adds no values. Is there some way to fix this?

I am using the following code:

Code:
eststo: ivreg2 checks_diff (mean_aid_pop75 = colony popratio75 col_popratio75) checks_first, r first savefirst savefprefix(checks1)

esttab checks* using "$out\first_stages_checks.tex",cells(b(star fmt(3)) se(par fmt(3))) label star(* 0.10 ** 0.05 *** 0.01) booktabs scalars(widstat j) title(First stage for the period 1975-2019 \label{reg1}) addnotes("All variables are means for for the period, except initial checks")replace
My data looks like this:
