schlather.vario: Variogram model of Schlather and Moreva

Description

The variogram model is $$\gamma(h) = \frac{[1+\{(\|h\|/\lambda\}^\alpha]^{\beta/\alpha}-1}{2^{\beta/\alpha}-1}, \quad 0 < \alpha \leq 2, \beta \leq 2.$$ The model is defined at \(\beta=0\) by continuity.

Usage

schlather.vario(h, alpha, beta, scale = 1)

Value

a vector or matrix of variogram values of the same length as h

Arguments

h

vector or matrix of pairwise distances

alpha

smoothness parameter

beta

shape parameter, must be less than 2

scale

scale parameter
