You set up a "tot" variable for each characteristic
For example:


gen race_tot=2408 if race==1
repl race_tot=159 if race==2
etc.

gender 1 2
gen gender_tot=1463 if gender==1
replace gender_tot=1547 if gender==2


gen age_tot =485 if age==1
replace age_tot=518 if age==2
etc.

THEN
in the -survwgt- statement, use totvars(race_tot gender_tot age_tot)


survwgt rake preweigh, by(race gender age) totvars(race_tot gender_tot age_tot) generate(newwt)

Hello,
I'm trying to figure out how to set up the totvars(varlist) part of the
survwgt command for raking my sample using age, race, and gender, where age
takes on 4 values, race takes on 4 values, and gender takes on 2 values. I
think I want to do:

survwgt rake preweigh, by(race gender age) totvars(varlist) generate (newwt)

I can't figure out how to set up the varlist for totvars with the values
for the marginals. The marginals are 2408 159 238 & 205 for race, 1463 &
1547 for gender, and 485 518 1139 & 868 for age.
