Hi Andrew,
IPF requires that the gender and party variables need to be numeric.
I shall tighten up this code but in the mean time use numbers for gender
and party and it should work
cheers

Hello All,
This seems like a straight forward example. But I don't understand why
it fails. I am using version 10.1
input str6 gender str8 party wgt
gender party wgt
male democrat 55
male repub 65
female democrat 50
female repub 30
end
. ipf [fweight = wgt], fit(gender + party)
Deleting all matrices......

marginal model 2 varlist : party
