create.new.toy.datasets: Create new toy datasets

In calibrator: Bayesian Calibration of Complex Computer Codes

Description

Creates new toy datasets, by sampling from an explicitly specified multivariate Gaussian distribution whose covariance matrix is that required for a Gaussian process.

Usage

create.new.toy.datasets(D1,D2,export=FALSE)

Arguments

export	Boolean, with default FALSE meaning to return toy datasets and TRUE meaning to return, instead, a list of the true values of the parameters
D1	D1; set of code run points
D2	D2; set of field observation points

Value

Returns a list of three elements:

y.toy
z.toy
d.toy

Note

Because function create.new.toy.datasets() calls computer.model() and model.inadequacy(), the datasets returned are drawn from a multivariate Gaussian distribution which is a Gaussian process
