I am using multiple imputation by chained equations on a logistic regression model; can I use Rubin's Rules to get CIs for the marginal effect?
I've got a binary outcome, 10-20 predictors (some numeric, some binary). There is one focal predictor. I would like to present the effect as a marginal effect (i.e., an adjusted prevalence difference),...
