Subject:      Survey data analysis

Dear SAS-L experts,

I am trying to calculate the difference of variables of interest between 2
years of survey data. I have proc surveymeans in SAS and I also have a SAS
compatible sofeware SUDAAN that specifically for survey analysis (never
used).  Now my question is how should I lay out the data? stack them with
indicator of year 1 and 2? or put them side by side and calculate the
differences first, then use proc surveymeans?  I hate to do the 2nd way if
I can avoid to do it.  Any advices?

Thanks in advance.

Sophia
