Where abs mean absolute value of numeric data. mean(abs(a-b))/mean(abs(a)) The matrices would look like this figure below, but instead of letter there are counted values of how often something occurs: Last edited by skipjack; October 22nd, 2019 at 11:02 AM.

A and B would be counted values, the values inside the matrix look like data that can be applied on a Fisher extract test.
