%description
Performs Bayesian posterior inference for heteroskedastic Gaussian
processes. Models are trained through MCMC including elliptical slice
sampling (ESS) of latent noise processes and Metropolis-Hastings sampling
of kernel hyperparameters. Replicates are handled efficientyly through a
Woodbury formulation of the joint likelihood for the mean and noise
process (Binois, M., Gramacy, R., Ludkovski, M. (2018)
<doi:10.1080/10618600.2018.1458625>) For large data, Vecchia-approximation
for faster computation is leveraged (Sauer, A., Cooper, A., and Gramacy,
R., (2023), <doi:10.1080/10618600.2022.2129662>). Incorporates 'OpenMP'
and SNOW parallelization and utilizes 'C'/'C++' under the hood.
