All,

Can anyone tell me how to test whether a single covariance (e.g., cov[x,y])
differs between two independent samples. I understand how to do the
parallel test for a correlation; it is discussed in Cohen & Cohen among
other places. I also understand how to do it with a SEM program. What is
the formula?

Thanks, Gene Maguin
