Add T to the proc surveymeans statement to request a t-test.

The Ratio statement would be used to indicate which variables to test.

Ratio x y / z t ; where x y z and t are variables will request tests for x with z, x with t, y with z and y with t.

If a variable appears on both sides to the / then the test of a variable with itself is ignored.

var cognitive_impairment /T;
domain education;
cluster raehsamp;

weight r7wtresp;

You can use Proc SURVEYREG to fit an ANOVA to complex survey data.

There are no procedures to fit non-parametric models, although I suppose you could apply SURVEYREG to the ranks. You would have to do a little research to see how this would be different from the SRS-world but it might be a possibility. I believe this book even discusses it although I don't recall where exactly in the book it is.
