  "Description": "Implements the Beta Kernel Process (BKP) for nonparametric\nmodeling of covariate-dependent binomial probabilities, and the\nDirichlet Kernel Process (DKP) for categorical or multinomial\nresponse data. Scalable global-local approximations are\nprovided through TwinBKP and TwinDKP, using twinning-selected\nglobal subsets and local nearest-neighbour updates. Functions\nare included for model fitting, predictive inference with\nuncertainty quantification, posterior simulation, and\nvisualization in one- and two-dimensional input spaces.\nGaussian, Matern 5/2, Matern 3/2, and Wendland kernels are\nsupported, with hyperparameters selected by multi-start\nderivative-free optimization. For more details, see Zhao, Qing,\nand Xu (2025) <doi:10.48550/arXiv.2508.10447>.",
