simul {hetGP}

Conditional simulation for CRNGP

Description

Conditional simulation for CRNGP

Usage

simul(object, Xgrid, ids, nsim, eps, seqseeds, check)

Arguments

object

CRNGP model

Xgrid

matrix of (x, seed) locations where the simulation is performed. Where all design locations are matched with all seed values. In particular, it is assumed that each unique x values is matched with all seeds before going to the next x value. The last column MUST correspond to seeds values. Xgrid must also contain the evaluated designs (e.g., in model$X0)

ids

vector of indices corresponding to observed values in Xgrid

nsim

number of simulations to return

eps

jitter used in the Cholesky decomposition of the covariance matrix for numerical stability

seqseeds

is the seed sequence repeated (e.g., 1 2 3 1 2 3), else it is assumed to be ordered (e.g., 1 1 2 2 3 3)

check

if TRUE, check that Xgrid has the proper structure (slower)

Value

Conditional simulation matrix.
