Thread Subject: Weighted paired t-test

Hi,

I wanted to perform a weighted paired t-test. In my understanding, the only difference between a weighted and unweighted t-test is the fact that for the weighted t-test I need to use the weighted mean (wmean) and the weighted variance. If this is so, then then should the following give me what I want?

wmap = wmean(data1-data2 ,W)./(sqrt(var(data1 - data2), W)/size(data1,1));

where W is a vector the size of data1 (and data2, since this is a paired t-test).

Many thanks in advance for your help,
T
