Hi,
A colleague of mine imputed data using SAS's mi command. The dataset, containing m=5 imputations, I translated into a .dta format using StatTransfer. I wondered if Stata's micombine command might be able to get the regression coefficients. I created the two variables _i and _j that normally would be present had we used Stata's mvis command instead of SAS's mi command and ordered the dataset as mvis would have.
I still get the following error message after using micombine.
. micombine regress s_mh dum1grp dum2grp gesl lft cd4 vload, impid (_j)
no row-identifier variable found - data may have incorrect format
r(198);
What format does Stata expect? Any help to sort this out will be greatly appreciated.
