SLGP: A package for spatially dependent probability distributions

Description

The SLGP package implements Spatial Logistic Gaussian Processes (SLGP) for the flexible modeling of conditional and spatially dependent probability distributions. The SLGP framework leverages basis-function expansions and sample-based inference (e.g., MAP, Laplace, MCMC) for efficient density estimation and uncertainty quantification. This package includes functionality to define, train, and sample from SLGP models, as well as visualization and diagnostic tools.

SLGP functions

The core functions in the package include:

  • slgp: trains an SLGP model from formula, data, and hyperparameters.

  • predictSLGP_moments: computes posterior predictive means and variances.

  • predictSLGP_quantiles: computes posterior predictive quantiles.

  • sampleSLGP: draws samples from the posterior predictive SLGP.

  • retrainSLGP: retrains a fitted SLGP object with new parameters or method.
