IsingSumLikelihood

Likelihood of sumscores from tractible Ising model.

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

IsingSumLikelihood(graph, thresholds, beta, responses = c(0L, 1L))

`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!
