krigeSTSimTB {gstat}

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
