rhoPowerExp: Powered Exponential Correlation Function

In geoCount: Analysis and Modeling for Geostatistical Count Data

Description

This function calculates the powered exponential correlation.

Usage

rhoPowerExp(u, a, k)

Arguments

u	a value which indicates the distance
a	a value which indicates the scale parameter, φ
k	a value which indicates the shape parameter, κ

Details

The function is \; \; ρ (u)=\exp ((-u/φ)^κ) \; \;.

When using the powered exponential correlation function, note that 0<κ<=2.

Value

A value of the correlation.
