The "SVR" commands are a set of commands I wrote to deal with estimation in 
complex samples using replication methods.  They are in many respects 
analogous to Stata's "SVY" commands, which handle complex samples using 
Taylor Series linearization.

Whichever approach you are using, to do a t-test, you use the -test- 
command after svrmean (or svymean), rather than the -ttest- command.

EG:

        . svrmean x
        . test x=2

        . svrmean x y
        . test x=y

And so on.

SEe the "test for svy" section of the SVY reference manual for more 
details.  (And note that you should be able to do everything there after 
the SVR commands, as well.)
