"The Mantel test, named after Nathan Mantel, is a statistical test of the correlation between two matrices. The matrices must be of the same dimension; in most applications, they are matrices of interrelations between the same vectors of objects. The test was first published by Nathan Mantel, a biostatistician at … See more The test is commonly used in ecology, where the data are usually estimates of the "distance" between objects such as species of organisms.

WebHere, we review the Mantel test and its variations, including Mantel correlograms and partial correlations and regressions. For illustrative purposes, we studied spatial genetic divergence among 25 populations of Dipteryx alata ("Baru"), a tree species endemic to the Cerrado, the Brazilian savannas, based on 8 microsatellite loci. WebMar 22, 2024 · The Mantel and Haenszel approach using the hypergeometric is more general in that it also applies to some cases in which the rows are not independent binomial samples from two populations. Examples are retrospective studies and randomized clinical trials with the available subjects randomly allocated to two treatments.
