spatialparsEst: spatialparsEst function...

Description

spatialparsEst function

Usage

spatialparsEst(gk, sigma.range, phi.range)

Arguments

gk

an R object; output from the function KinhomAverage or ginhomAverage

sigma.range

range of sigma values to consider

phi.range

range of phi values to consider

Value

• rpanel function to help choose sigma nad phi by eye

Details

Having estimated either the pair correlation or K functions using respectively ginhomAverage or KinhomAverage, the spatial parameters sigma and phi can be estimated. This function provides a visual tool for this estimation procedure.
