simulate.gp {spectralGP}R Documentation

Simulates a process realization from a spectral GP object

Description

Simulates a process realization by drawing a random draw of coefficients from their prior distribution and updating the process values.

Usage

simulate.gp(object,...)

Arguments

object A GP object, created by gp.
... Other arguments.

Details

Modifies the coeff and process elements of the object.

Value

The function modifies the GP object, which is essentially a pointer (an R environment in this case), so NULL is returned.
