%description
Fits Bayesian hierarchical spatial process models for point-referenced
Gaussian, Poisson, binomial, and binary data using stacking of predictive
densities. It involves sampling from analytically available posterior
distributions conditional upon some candidate values of the spatial
process parameters and, subsequently assimilate inference from these
individual posterior distributions using Bayesian predictive stacking. Our
algorithm is highly parallelizable and hence, much faster than traditional
Markov chain Monte Carlo algorithms while delivering competitive
predictive performance. See Zhang, Tang, and Banerjee (2024)
<doi:10.48550/arXiv.2304.12414>, and, Pan, Zhang, Bradley, and Banerjee
(2024) <doi:10.48550/arXiv.2406.04655> for details.
