Dear Statalisters,

I have a question about how to use expand to adjust sampling weight
for the command that pw is not allowed to use. I know previous
discussion from this link
http://mail.google.com/mail/?hl=en&shva=1#search/expand+weight/12b6754ba71c32bd
 talks some points about expand. But I am still not sure how to use
it.

Suppose I have there variables in the data set:X,Y, and sampling
weight. In order to use stata command that does not allow to use pw, I
am thinking to expand the data set according to weight.

------------------------------
X             Y            sweight
1              2             10
2              2.5           2
.....................
-----------------------------
Is it correct if I use
. gen tt_weight=sum(weight)
. expand sweight/tt_weight                          ?

Thanks for your help!

Sincerely,
Amanda
