I am sure you will get helpful answers. I am almost as sure that you shouldn't be doing this. I suggest you consult with your local statistician.

I want to run a t-test across the list for each component in the matrix. For example, the first t-test is on myList[[1]][1, 1], myList[[2]][1, 1], ..., myList[[9]][1, 1]; and there are totally 15X15 t-tests. How can I run these t-tests in a simple way?
