IsingLikelihood {IsingSampler}R Documentation

Likelihood of all states from tractible Ising model.

Description

This function returns the likelihood of all possible states. Is only tractible up to rougly 10 nodes.

Usage

IsingLikelihood(graph, thresholds, beta, responses = c(0L, 1L),
                 potential = FALSE)

Arguments

graph

Square matrix indicating the weights of the network. Must be symmetrical with 0 as diagonal.

thresholds

Vector indicating the thresholds, also known as the external field.

beta

Scalar indicating the inverse temperature.

responses

Response options. Typically set to c(-1L, 1L) or c(0L, 1L) (default). Must be integers!

potential

Logical, return the potential instead of the probability of each state?
