abstract: Fits spatial item factor analysis models for binary responses, following
  Chacón-Montalván, E. A., Parry, L., Giorgi, E., Torres, P., Orellana, J. D. Y.,
  Moraga, P., and Taylor, B. M. (2025) <https://doi.org/10.1214/25-AOAS2072>, using
  full Bayesian inference via adaptive Metropolis-Hastings within Gibbs sampling and
  auxiliary variables with a probit link function. The latent factors are modelled
  as the sum of a predictor effect, a multivariate Gaussian process capturing spatial
  dependence, and a multivariate non-spatial term, allowing users to fit and predict
  spatially-referenced constructs such as food insecurity or socioeconomic indices.
  Standard exploratory and confirmatory item factor analysis are supported as particular
  cases, simply by dropping the spatial structure.
