title: 'dmrfit: Scalable Bayesian Inference for Discrete Markov Random Fields'
version: 0.1.1
doi: 10.32614/CRAN.package.dmrfit
abstract: Estimation of discrete Markov random fields through the pseudo-likelihood,
  for both Ising models (Ising (1925) <https://doi.org/10.1007/BF02980577>) and ordinal
  Markov random fields (Marsman et al. (2025) <https://doi.org/10.1017/psy.2024.4>).
  Point estimates, either maximum pseudo-likelihood or maximum a posteriori, are obtained
  through a trust region optimization algorithm, with robust standard errors from
  the Godambe-Huber-White (GHW, or sandwich) estimator, for both full and constrained
  network structures. Bayesian inference corrects the pseudo-posterior through coordinate
  rescaling (Arena and Marsman (2026) <https://doi.org/10.48550/arXiv.2601.17205>),
  which matches its covariance to the GHW covariance, and samples from it with the
  Fisher adaptive Metropolis-adjusted Langevin algorithm (Titsias (2024) <https://doi.org/10.48550/arXiv.2305.14442>).
  For comparison, the posterior based on the full likelihood can also be sampled,
  exactly for small networks or with the double Metropolis-Hastings algorithm (Liang
  (2010) <https://doi.org/10.1080/00949650902882162>). Savage-Dickey Bayes factors
  test each pairwise interaction, computed either by sampling importance resampling
  (Skare et al. (2003) <https://doi.org/10.1111/1467-9469.00360>) or from the posterior
  draws.
