krigeSimCE: Simulation based on circulant embedding
Description
Simulating a conditional/unconditional Gaussian random field via kriging and circulant embedding
Usage
krigeSimCE(formula, data, newdata, model, n = 1, ext = 2)
Value
A spatial data frame as defined in newdata
with n
simulations.
Arguments
- formula
the formula of the kriging predictor
- data
spatial data frame that conditions the simulation
- newdata
locations in space where the Gaussian random field shall be simulated
- model
a vgm model that defines the spatial covariance structure
- n
number of simulations
- ext
extension factor of the circulant embedding, defaults to 2
