Create a linear kernel specification

Create a linear kernel specification

Usage

linear_kernel(variance = 1)

Arguments

variance

Positive variance multiplier.

Value

An object of class gaussianprocesses_kernel.

Stability

Stable: from version 1.0.0 this interface changes incompatibly only in a major release, after a deprecation period. Results and options that concern an experimental model class, kernel, or argument follow that interface's tier. See gaussianprocesses-package for the policy.

See also

kernel_linear() computes the same covariance directly from parameter values, without a kernel specification.

Examples

# A linear trend component.
evaluate_kernel(linear_kernel(variance = 0.1), 1:4)
#>      [,1] [,2] [,3] [,4]
#> [1,]  0.1  0.2  0.3  0.4
#> [2,]  0.2  0.4  0.6  0.8
#> [3,]  0.3  0.6  0.9  1.2
#> [4,]  0.4  0.8  1.2  1.6
