In spatialwarnings: Spatial Early Warning Signals of Ecosystem Degradation

Description

This function computes the Moran's I index of spatial correlation at lag 1.

Usage

raw_moran(mat)

Arguments

mat

A matrix

Details

This function returns the spatial correlation as measured by the Moran's I index. If the variance of the matrix is zero, then NaN is returned.

Value

The Moran's I numeric value as a numeric number.
