Sounds like 

mean var2 [fweight = var1]

is for you, if you want the mean of the dummy var2, considering frequency
weights var1. It is weird, though, that you are asking for "...confidence
intervals of these variables...". Really, only the dummy variable is
amenable to this kind of calculation...

Hope this helps,

Betreff: st: Confidence intervals

I have a dataset with one variable representing weights and another 
representing dummy ones (just zeros and ones).

I need to calculate confidence intervals of these variables considering 
the weights. How do I do?

Thanks in advance
