Hello good morning; I have a problem and I do not know how to solve it. I understand that, through SurveySelect, but I don't know how to plant it, I've been thinking about it for days, and I don't see the light! I have a Data Base of 150,000 records and I have to select a subsample of the Data Base of 85,000 records, one for each household, according to a series of variables. The stratum variables are Household ID Sex Age It is about selecting 85,000 cases out of 150,000 that meet the following conditions - A single record per household (there are 85,000 households) - 50% men and 50% women approximately - Proportional for age groups (10% between 18 and 25 years old, 10% between 25 and 35 years old, etc.) Can someone help me, I will be eternally grateful.
