My mi impute chained model (which contains both dummy and continuous variables imputed with (regress) and (logit) respectively is failing to converge due to perfect prediction. I have deduced that the problem variables are all the categorical variables that are part of interaction terms. These are a collection of continuous x continuous, continuous x binary and binary x binary variables. I know I should impute these but I am not sure if I should list them after (regress) or (logit)? I tried to both list them after (regress) and (logit) but no success.
Where do I include these three type of interaction variables in the imputation command?
Augment both within the parentheses and at the end is not helping either.
Here is my code with all the variables registered if it is any help (I am using stata 12):
