pkern_pars: Initialize covariance kernel parameters for grid 'g'

In deankoch/pkern: Fast Kriging with Product Kernels

Initialize covariance kernel parameters for grid g

Description

Returns a kernel parameter list defining the covariance model for g, with default initial values assigned to parameters based on the grid dimensions and sample variance of observed data.

Usage

pkern_pars(g, pars = "gau", fill = "initial")

Arguments

g	list, a pkern grid definition (or object accepted by pkern_grid)
pars	character or list defining kernels (in form understood by pkern_pars_make)

Details

Swap fill='initial' with 'lower' and 'upper' to get default lower and upper bounds.

Value

a list defining separable covariance parameters

Examples

pkern_pars(g=10)
pkern_pars(c(10,15))
pkern_pars(c(10,15), 'mat')
pkern_pars(c(10,15), 'mat', 'upper')
