You would do this in your data, for example by: **************************** egen stratum =group(year stk) ***************************** If there were 10 strata in 2006 and 10 in 2007, the new stratum variable should have 20 levels. Then a single -svyset- statement will allow joint analysis of the two surveys, as in my example. Steve sjsamuels@gmail.com
