varobj: Function for variogram fitting

In edzer/vardiag: Variogram Diagnostics

Description

This function fits a variogram model to spatial data and calculates some statistics.

Usage

varobj(m, iter = 50, tolerance = 2e-04, trace = 1, loo = FALSE)

Arguments

m	n by 3 matrix with spatial data
iter	this argument is put forward to the optimization routine
tolerance	this argument is put forward to the optimization routine
trace	if set to values higher than 1 some debug messages are given
loo	if set to TRUE, leave-one-out residuals are clculated

Details

Only spherical variogram models are fitted.

Value

a variogram object
