Hi,I have the following problem: I have a large multi country data file from which I want to export a random sample of about 20% of the cases of each country.
Can I achieve this with the following temporary and the sample commands ? SORT CASES by country. SPLIT FILE by country. TEMP. Sample .2 . COMPUTE selection = 1. FREQ selection. SPLIT FILE OFF Thanks for any hints. - ftr
