krigeSTSimTB: conditional/unconditional spatio-temporal simulation

In gstat: Spatial and Spatio-Temporal Geostatistical Modelling, Prediction and Simulation

conditional/unconditional spatio-temporal simulation

Description

conditional/unconditional spatio-temporal simulation based on turning bands

Usage

krigeSTSimTB(formula, data, newdata, modelList, nsim, progress = TRUE, 
             nLyrs = 500, tGrid = NULL, sGrid = NULL, ceExt = 2, nmax = Inf)

Arguments

formula	the formula of the kriging predictor
data	conditioning data
newdata	locations in space and time where the simulation is carried out
modelList	the spatio-temporal variogram (from vgmST) defining the spatio-temporal covariance structure of the simulated Gaussian random field
nsim	number of simulations
progress	boolean; whether the progress should be shown in progress bar
nLyrs	number of layers used in the turning bands approach (default = 500)
tGrid	optional explicit temporal griding that shall be used
sGrid	optional explicit spatial griding that shall be used
ceExt	expansion in the circulant embedding, defaults to 2
nmax	number of nearest neighbours that shall e used, defaults to 'Inf' meaning all available points are used

Value

a spatio-temporal data frame with nSim simulations
