Kriging Simulation
Description
(Conditional) Simulate at given locations, with a model fit resulting from modelKriging
.
In contrast to prediction or estimation, the goal is to reproduce the covariance
structure, rather than the data itself. Note, that the conditional simulation
also reproduces the training data, but
has a two times larger error than the Kriging predictor.
Usage
## S3 method for class 'modelKriging'
simulate(
object,
nsim = 1,
seed = NA,
xsim,
conditionalSimulation = TRUE,
returnAll = FALSE,
...
)
Arguments
object |
fit of the Kriging model (settings and parameters), of class |
nsim |
number of simulations |
seed |
random number generator seed. Defaults to NA, in which case no seed is set |
xsim |
list of samples in input space, to be simulated |
conditionalSimulation |
logical, if set to TRUE (default), the simulation is conditioned with the training data of the Kriging model. Else, the simulation is non-conditional. |
returnAll |
if set to TRUE, a list with the simulated values (y) and the corresponding covariance matrix (covar) of the simulated samples is returned. |
... |
further arguments, not used |
Value
Returned value depends on the setting of object$simulationReturnAll
