untitled spatial correlation implementation

Usage

usci(a, b, a_x, a_y, b_x, b_y, scale_fact)

Arguments

a

vector of values for observation set \(A\)

b

vector of values for observation set \(B\)

a_x

x-axis coordinates for observation set \(A\)

a_y

y-axis coordinates for observation set \(A\)

b_x

x-axis coordinates for observation set \(B\)

b_y

y-axis coordinates for observation set \(B\)

scale_fact

scale factor for negative exponential kernel

Value

spatial correlation metric \(c\)

Examples

set.seed(8)

a_n <- 128
b_n <- 256

a <- rpois(a_n, runif(1, 0, 32))
a_x <- rnorm(a_n)
a_y <- rnorm(a_n)

b <- rpois(b_n, runif(1, 0, 32))
b_x <- rnorm(b_n)
b_y <- rnorm(b_n)

usci(a, b, a_x, a_y, b_x, b_y, 1e-1)
