%description
Bayesian factor models are effective tools for dimension reduction. This
is especially applicable to multivariate large-scale datasets. It allows
researchers to understand the latent factors of the data which are the
linear or non-linear combination of the variables. Dynamic Intrinsic
Conditional Autocorrelative Priors (ICAR) Spatiotemporal Factor Models
'DIFM' package provides function to run Markov Chain Monte Carlo (MCMC),
evaluation methods and visual plots from Shin and Ferreira
(2023)<doi:10.1016/j.spasta.2023.100763>. Our method is a class of
Bayesian factor model which can account for spatial and temporal
correlations. By incorporating these correlations, the model can capture
specific behaviors and provide predictions.
