Question about the imputation returns negative values. #413

Hello everyone,

I am trying to impute missing data by using mice( ). It works well, but it returns negative values for a variable that should be positive. I don't know how to solve this problem.

Hope for anyone's reply. Many thanks!

Imputation method mice.impute.pmm() will never return values that are not observed, so using that method should solve your problem.
