get_covariance_matrix.ModelTree: Get the Covariance Matrix for a Kernel ModelTree

In mattdneal/gaussianProcess: Gaussian Process Fitting and Prediction

Description

Get the Covariance Matrix for a Kernel ModelTree

Usage

## S3 method for class 'ModelTree'
get_covariance_matrix(kernel, x, sigma.n, hyper.params,
  additional.params = list(), cache = NULL)

Arguments

kernel	A ModelTree object
x	A matrix of data to find the covariance matrix of
sigma.n	The standard deviation of the noise to add to the kernel - used to regularise the resulting covariance matrix
hyper.params	The hyperparameters of kernel
additional.params	an empty list (not used for ModelTree objects)

Value

A covariance matrix
