Modifications of the Cauchy Family Covariance Model

Description

RMcauchytbm() is a shortcut of RMtbm(RMgencauchy()) and is given here for downwards compatibility

Usage

1
RMcauchytbm(alpha, beta, gamma, var, scale, Aniso, proj)

Arguments

alpha,beta

see RMgencauchy.

gamma

is the same as fulldim in RMtbm.

var,scale,Aniso,proj

optional arguments; same meaning for any RMmodel. If not passed, the above covariance function remains unmodified.

Value

RMcauchytbm returns an object of class RMmodel
