I've restored the original exchange which helps understand my suggestion. You deleted it unnecessarily. -tabdisp- circumstantial? I think you mean some quite different word. That said, here is a stupid example to illustrate what I meant. . sysuse auto, clear . table fore rep78 [pw=length], c(mean mpg) ------------------------------------------------------- | Repair Record 1978 Car type | 1 2 3 4 5 ----------+-------------------------------------------- Domestic | 20.8571 18.9404 18.7088 17.9804 31.9625 Foreign | 23.218 24.7492 25.8125 ------------------------------------------------------- . bysort foreign rep78 : gen n = _N . table fore rep78 [pw=length], c(mean mpg min n) ------------------------------------------------------- | Repair Record 1978 Car type | 1 2 3 4 5 ----------+-------------------------------------------- Domestic | 20.8571 18.9404 18.7088 17.9804 31.9625 | 2 8 27 9 2 | Foreign | 23.218 24.7492 25.8125 | 3 9 9 ------------------------------------------------------- The trick is this: 1. The created variable -n- is actually a constant within groups of -foreign rep78-. 2. Specifying the minimum (or the maximum) is a way to avoid the pweights being applied. (I don't get your distinction between n and frequency, but the trick remains valid for any other variable constant within groups, so far as I can see.) Nick [email protected] Denise Sengül Thanks for replying Nick. But I don't really get what you mean. -tabdisp- is way too circumstantial in my case. I've got tables of the form table var1 var2 [pweight=wei], c(mean var3) So now I'm trying to add unweighted n's (not frequencies, got it wrong) I don't really know what you mean by "put unweighted frequencies in another variable". Since I want the n's to be displayed for each group in the table, that doesn't really make sense in my head. But please correct me. Nick Cox Put the unweighted frequencies in another variable and then have one of your statistics something like "min freqname". My guess is that the minimum of those frequencies is invariant under pweighting. Alternatively, switch to -tabdisp- where you have more control. Denise Sengül does anyone know how to get pweighted means but unweighted frequencies together in one table (produced with 'table')? I ideally want separate columns, one of them containing the frequencies, the other one containing the means. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
