Web21 jan. 2013 · This toolbox implements kriging based regression (also known as Gaussian process regression) and optimization of deterministic simulators. The toolbox consists of two main components: 1. functions for creation of kriging model for deterministic or noisy data (correlation kernels, hyper-parameter estimation, prediction, cross validation). 2. WebKriging uses probability and spatial correlation to create a surface that is weighted by observed values through a distance- and direction-based semi-variance function that can account for anisotropic spatial patterns and trends …
