Dear statalist - I have a dataset where we have participants who have
completed VERBAL and PERFOMANCE IQ tests and one simply question is
which is higher (all one group) verbal or performance. I use the
following code to run a paired t-test:

ttest wisc_piq == wisc_viq

The design is a sample one with weights how do I run a weighted paired
t-test (using pweight or aweights I am assuming?).

Many thanks in advance for any help...

Tony
