Unable to display first-stage estimates; macro e(first) is missing

[hatsune miku]

Hello everyone, I use this code using the data panel, but the results don't come out and it says that Unable to display first-stage estimates; macro e(first) is missing
thank you in advance

eststo model_1: regress short_phys ever_attend_tk, vce(robust)

eststo model_2: regress short_phys hhsize yos mother_work gender birthwt jawa pulau_jawa citizens Askeskin_receiver ever_attend_tk, vce(robust)

eststo model_3: ivreg2 short_phys ///
(ever_attend_tk = zwealth), robust first

eststo model_4: ivreg2 short_phys hhsize yos mother_work gender birthwt jawa pulau_jawa citizens Askeskin_receiver ever_attend_tk ///
(ever_attend_tk = zwealth), robust first

esttab model_1 model_2 model_3 model_4 using "TK_2013.rtf", replace label se(3) b(3) star(* 0.1 ** 0.05 *** 0.01) r2(3) obslast

estout is from SSC (FAQ Advice #12). You should show the actual Stata output. I don't see anything obviously wrong, does the following work for you?

webuse hsng2,clear
eststo: ivreg2 rent pcturban (hsngval hsnggrow = faminc i.region), first savefirst savefprefix(st1)
esttab st1*, nobaselevels

If not, update estout.

ssc install estout, replace

just realized I put ever_attend_tk twice here:
eststo model_4: ivreg2 short_phys hhsize yos mother_work gender birthwt jawa pulau_jawa citizens Askeskin_receiver ever_attend_tk ///
(ever_attend_tk = zwealth), robust first

thank you for your help!!!

and anyway I have another question when i ran this code
asdoc ivreg2 short_phys (ever_attend_tk = zwealth), save(Endogenity.doc)

there always appears 5.503657307613117, not found
r(111);

any solution?
thank you so much!

Sorry, I do not use asdoc from SSC to output regression results, so I do not have an answer for you. Start a new thread with asdoc in the title and users of that command may be able to help you.
