AD.dist {nsRFA} | R Documentation

## 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

### Details

The Anderson-Darling statistic used here is the one defined in http://en.wikipedia.org/wiki/Anderson-Darling_test as A2.

### Value

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

    annualflows
    summary(annualflows)
    x <- annualflows["dato"][,]
    cod <- annualflows["cod"][,]

    # Ad.dist
    AD.dist(x,cod)             # it takes some time
