[Impute] Specifying diiferent maximum and minumum values on a variable for different groups

Hi Everyone,

 

I was wondering if it’s possible to specify different minimum and maximum values on a variable for different groups in a dataset using IVEware or SAS Proc MI or some other program. For example, I’m imputing start and stop dates for HIV antiretroviral drugs and would like to impose one set of restrictions for cases where the start is unknown, the stop is unknown, and the range of possible start and stop dates overlap, and another set of restrictions for all remaining cases.

 

Thanks,

 

Paul
