Thank you for your prompt reply and apologies for omitting the syntax. I had typed:
eststo BMImsw: svy, subpop(pop2w): reg logYw4 /*incW4*/ BMI currwkW4 MDcurrwkW4 tenW4 MDtenW4 malew1 ///
blackhw1 hisphw1 raceother ageW4 agesqW4 totchild MDtotchild peduyw1 MDpeduyw1 eduyw4 /*lowbrthwt*/ exercisew4 ///
hlthinW4 vocabStdW1 region1 region2 region3 depressw4 marriedw4
Many thanks,
Sumedha.
