Comparison of correlation coefficients
Hi, I calculated a few correlation coefficients. Now I want to know whether they are different from each other. Is there an R package that can do such a comparison? Thanks for any suggestion. Best, Donglei Hu Department of Medicine UCSF [[alternative HTML version deleted]]
