%description
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) <doi: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.
