Thank you, Tom, you guided me on how to say what I mean   I have one variable (call it Diss) in my dataset that defines patients with disease A, and is filled with Yes or No.   I want a sample where the relative frequencies of males and females in the sample are different and using the complete dataset. the expected matching ratio is like F: M (20:80) and for M: F (20:80).   table 2x2 represents the comparison after sampling so that the table will contain percentage results for gender F with Diss valued Yes and No, and likewise with gender M.   Do I now explain well what I want?  Thank you. ...

I am sorry Reeza, could you please give me the example? I want to see how many% of patients if I use my data randomly for simple random sampling so that it will produce a comparison table F to F a percentage of 20 for the results of yes and no, F to M with a percentage of 80; and vice versa with M, as I have written above. Do you mean I have to generate my data to make a sample table? Forgive me if I do not understand. Please give me an explanation. Thank you. ... View more

Hello ... everyone. I'm a beginner at using SAS. I need help with the problem I am facing with the data process I am doing. I have 900,000 observations without duplication of data, where this data consists of the variables id, id_sex, visit date, disease (which I have processed so that it will contain yes or no, 1/0). From this data I want to try to make a comparison with a certain percentage and use simple random sampling without replacement with the following comparison and desired results: F  --- 20% -------> F F  --- 80% ------->M M --- 20% ------->M M --- 80% ------->F   and the expected results table is like this: Gender Yes No F ……. % ……. % M ……. % ……. %   Could anyone help me, please?  Thank you for your kindness.   Regards,     ...
