Bivariate Moran's I using Lee's L measurement

Source: R/sca.R

Calculate bivariate Moran's I using Lee's L measurement.

LeeL(X, W)

Arguments

X

A matrix with observations as rows and features as columns.

W

A weight matrix across all observations, i.e inverse of a pairwise distance matrix.

Value

A spatial cross-correlation matrix.

Examples

{
data.use <- quakes[1:100,]
W <- 1/as.matrix(dist(data.use[,1:2]))
diag(W) <- 0
L <- LeeL(data.use[,3:4], W)
}
