stripes

The synthetic "stripes" provides a set of training and test data.frame of a Gaussian process realization with a (inherently sparse) nonstationary covariance function.
Several stripes are present in the training dataset, and the task is to predict them.

datasets

Estimation, prediction, and simulation of nonstationary Gaussian process with modular covariate-based covariance functions.
Sources of nonstationarity, such as spatial mean, variance, geometric anisotropy, smoothness, and nugget, can be considered based on spatial characteristics.
An induced compact-supported nonstationary covariance function is provided, enabling fast and memory-efficient computations when handling densely sampled domains.
