AD.dist: Anderson-Darling distance matrix for growth curves

Description

Distance matrix for growth curves. Every element of the matrix is the Anderson-Darling statistic calculated between two series.

Usage

AD.dist (x, cod, index=2)

Arguments

x

vector representing data from many samples defined with cod

cod

array that defines the data subdivision among sites

index

if index=1 samples are divided by their average value; if index=2 (default) samples are divided by their median value

Value

AD.dist returns the distance matrix between growth-curves built with the Anderson-Darling statistic.

Details

The Anderson-Darling statistic used here is the one defined in http://en.wikipedia.org/wiki/Anderson-Darling_test as \(A^2\).
