Dear All,
I have used the pwcorr command to get correlation coefficients and I am
interested in finding the difference in the coefficients and the
significance of the difference.
For example if I have 3 variables y1 y2 and x2 and then I do
pwcorr y1 x2 to get r1 and pwcorr y1/y2 x2 to get r2. If there is an
improvement in r as a result of using y1/y2 then how to account for the
improvement together with its significance. Is there anyway way I can do so
using STATA?
Many thanks
