GibbsMPLE: Maximum Pseudo-Likelihood potentials estimate.

In VicFreguglia/GibbsRF: Tools for Gibbs Random Fields models

Description

Potentials estimate via Maximum Pseudo-Lilelihood.

Usage

GibbsMPLE(X, gModel, type = "symetric", ...)

Arguments

X	a matrix, realization of a GibbsModel.
gModel	A GibbsModel object, vMat and cMat value should be NULL. If the object has non-NULL vMat or V values, they'll be ignored.
type	Wich type of Energy function to be considered. "general" indicates all potentials are free. "symetric" indicates differences of the same absolute value have the same potential value. "equal" indicates all non-zero differences potentials have the same value.
...	arguments to be passed to the optim() function during maximization.

Value

A GibbsModel object with the estimated vMat and V potentials values.
