R: Mantel test
WebThe Mantel test is widely used to test the linear or monotonic independence of the elements in two distance matrices. It is one of the few appropriate tests when the … WebFor the Mantel test, the z score is the sum of the products of the corresponding elements of the matrices...so don't confuse it with the standard z-score based on the normal distribution. The problem with the z-score (sensu Mantel) is that the value depends on the magnitude of your measured variables (kind of like covariance) and is, thus, hard ... call the gutter guys
