Hi everyone, I have a question regarding randomly subsetting the data based on predetermined unequal probabilites. Is there any technique or SAS procude that would help me accopmplish this? For example I have a data with 1000 subjects, and subjects are assigned probabilties that varies across individuals. Based on these probailities I would like to randomly select 100 subjects. How would I do this?
If I understand what you want, your probabability value could be used as a SIZE parameter in Proc surveyselect and use one of the probability proportionate to size selection methods such as PPS.
