Implements maximum likelihood estimation for Gaussian processes, supporting both isotropic and separable models with predictive capabilities. Includes penalized likelihood estimation following Li and Sudjianto (2005, <doi:10.1198/004017004000000671>), using decorrelated prediction error (DPE)-based metrics, motivated by Mahalanobis distance, that account for uncertainty. Includes cross validation techniques for tuning parameter selection. Designed specifically for small datasets.
