st: RE: Statistical test comparing two nonindependent variances?

["Anderson, Bradley J" <BAnderson1@lifespan.org>]

A colleague wants to test the hypothesis that the variance of X1 is not
equal to the variance of X2.  X1 and X2 are measured on the same scale of
measurement in the same sample.  I know of the F-test for comparing two
variances from independent samples, but can't seem to come up with anything
that is appropriate in this case.  Perhaps I'm just ignorant.  Thanks!
