\title{
Entropy of the Ising Model
}
\description{
Returns (marginal/conditional) Shannon entropy of the Ising model.
}
\usage{
IsingEntropy(graph, thresholds, beta = 1, conditional = numeric(0),
          marginalize = numeric(0), base = 2, responses = c(0L, 1L),
          delta = 0)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{graph}{
Weights matrix
}
  \item{thresholds}{
Thresholds vector
}
  \item{beta}{
Inverse temperature
}
  \item{conditional}{
Indices of nodes to condition on
}
  \item{marginalize}{
Indices of nodes to marginalize over
}
  \item{base}{
Base of the logarithm
}
  \item{responses}{
Vector of outcome responses.
}
  \item{delta}{
Optional per-node quadratic (Blume-Capel) term added to the Hamiltonian as \code{delta_i * s_i^2}; a single value (recycled over nodes) or one value per node. The default \code{0} corresponds to the ordinary Ising model. See \code{\link{BlumeCapelSampler}}.
}

\note{
The old (misspelled) name \code{IsingEntrophy} is deprecated; use
\code{IsingEntropy} instead. \code{IsingEntrophy} is retained as a thin
wrapper that emits a deprecation warning and forwards to \code{IsingEntropy}.
