I have a data base with 2 different test scores and two groups, a treatment
group and a control group. I have managed to test whether the mean of each
test scores is different among the two groups using svymean and then lincom
in this way:

svy: mean testA, over(treatment)
lincom [testA]1-[testA]0

svy: mean testB, over(treatment)
lincom [testB]1-[testB]0

What I want to do is jointly test whether both variables (testA and testB)
are jointly statistically different among the two groups, but incorporating
the sample design in my estimation.
