The Mantel test, named after Nathan Mantel, is a statistical test of the correlation between two matrices. The matrices must be of the same rank, 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 the National Institutes of Health, in 1967. Accounts of it can be found in advanced statistics books (e.g., Sokal & Rohlf 1995).
Famous quotes containing the word test:
“It is the test of a novel writer’s art that he conceal his snake-in-the-grass; but the reader may be sure that it is always there.”
—Anthony Trollope (1815–1882)
