%description
Implements the Beta Kernel Process (BKP) for nonparametric modeling of
spatially varying binomial probabilities, together with its extension, the
Dirichlet Kernel Process (DKP), for categorical or multinomial data. The
package provides functions for model fitting, predictive inference with
uncertainty quantification, posterior simulation, and visualization in
one-and two-dimensional input spaces. Multiple kernel functions (Gaussian,
Matern 5/2, and Matern 3/2) are supported, with hyperparameters optimized
through multi-start gradient-based search. For more details, see Zhao,
Qing, and Xu (2025) <doi:10.48550/arXiv.2508.10447>.
