Survey Analysis: Missing Values with respect to 1 group of respondents

[Carson Richardson]

Hi all, I would like to know if there is a way to fill in missing values with respect to only 1 subset of responders. I.e., I have two groups of responders, but I'm only interested in the missing values of 1 of them (to keep proportions equal, one group of responders is much larger than the other). I know exactly how many people responded in my target group, this is stored in a variable, I just can't figure out how to use only missing data with respect to that variable. Thanks in advance for your help.

Actually, I realized it was as simple as using an if statement, and using the m option after. Thanks anyways!
