st: Quantiles and variance with pweight

[Adam Cheung <adam_kalok@yahoo.com.hk>]

Dear all, 

I am trying to do some descriptive analysis with some variables (e.g. income). I would like to look at different quantiles, median and the variance of the variables. However, my data oversampled certain groups of people, therefore pweight is needed. 

Without weighting, I know sum Y, de can already do all the things I want. But I don't know how to do the same thing, if weighting is required. Is it still statistically appropriate to talk about properties such as quantiles, median and variance under weighting? 

Thanks a lot,
Adam
