I am trying to find a statistical approach to comparing the differences between matrices in a 3D matrix. I have a 3D matrix of m,n,z and I would like to look have a statistical measure (ideally a m,n matrix) that shows where the matrices most differ or are statistically different from their mean value.
I have come across a few tests from the statistical tool box that do this between two matrices, or even between 2 3D matrices, but I am not sure how to apply it to one 3D matrix. Perhaps a t-test (normalized by the mean) along the z axis that produces a mxn matrix of p-values would work here.
Hope my question makes sense.
