Hi, I have a conceptual question about raking weights. I have a survey sample drawn from a known population. I used the population demographics sex, race, and age (I know these numbers but don't have the population dataset). SO using these population frequencies, I created raking weights for my sample. I used:
ipfraking [pw=1], generate(rakedwgt) ctotal(PRData_age PRData_gender PRData_race)
I don't have any sample weight variable and according to others' suggestion I used pw=1 in this case.
It looks like this:
Summary of the weight changes
| Mean Std. dev. Min Max CV
--------------+--------------------------------------------------
Orig weights | 1 0 1 1 0
Raked weights | 413.7 968.1 .8696 11144 2.34
Adjust factor | 413.6847 0.8696 1.11e+04
So after applying the raking weight to my sample, the proportions look similar to what I expected but the count is showing same as main population instead of being similar to the survey dataset frequencies.
So when I created both weighted and unweighted tables for my variables, the unweighted N is what's in the actual survey dataset, while the weighted numbers are similar to whole population N. What should I do to adjust the raked weights?
