I am using the Complex Samples procedure in SPSS ver. 21 and would like some feedback on an issue. I would like to calculate prevalence rates for a dichotomous outcome by a single target ordered categorical predictor. As part of this analysis, however, I would like to control for two other categorical variables, so that the relationship between the target predictor and outcome are adjusted. Any advice on methods within the Complex Samples procedure would be helpful. Thanks!
