raw_cg_moran: Moran's Index at lag of 1

In spatialwarnings: Spatial Early Warning Signals of Ecosystem Degradation

Moran's Index at lag of 1

Description

This functions computes the Moran's spatial correlation index (with lag one) on a matrix.

Usage

raw_cg_moran(mat, subsize = 1)

Arguments

mat	A matrix
subsize	logical. Dimension of the submatrix used to coarse-grain the original matrix (set to 1 for no coarse-graining).

Value

The Moran's I index measuring autocorrelation at lag 1 as a named vector
