I have a survey data set with missing values and I generated 5 multiple imputations in which the missing values were imputed. I'd like to see if there's any association among categorical variables using chi-squared test. I was able to run chi-squared test on each imputed data set using in SAS using proc surveyfreq, however, I do not know how to combine the results. Can anyone walk me through the process on how to test the associations between these categorical variables?
