st: multiple imputation
I am trying to do multiple imputation using ICE in stata. My variable to be
imputed is a continuous variable for measuring depression (Hamilton Rating
Scale). When I do the imputation based on some predictor variables and week
number, I am getting negative values for some of the missing values which
are not possible because my variable is always positive. I tried a different
combination of predictors and interaction terms but I keep getting negative
values. Do you have any suggestion or idea to why this is happening?
Any help is appreciated. Thanks
