I strongly disagree with the philosophy of looking at 600 p-values (and most likely picking off the largest ones). This is poor statistics and poor science. Please read something on multiplicity and why this is bad news. A recent paper in the Lancet showed that eating cereal in the first trimester increased the probability of a male baby to 0.55. They had done 262 tests on various diets and found the most significant one. A plot of the p-values (done by a critic of the paper) showed a perfect straight line when comparing the p-values with a line of slope 1. I strongly suggest you abandon this approach. Tony Peter A.

It is very difficult to record all the p values by the following command >pwcorr v1 v2, sig Does anyone know how to record it automatically? Any advice will be very much approciated.
