AD.dist: Distance matrix for growth curves

Description

Distance matrix for growth curves.

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.
