generateEnsembleFromUncertainty: Create an ensemble from an uncertainty and AR1 estimate

In nickmckay/GeoChronR: Tools to Analyze and Visualize Time-Uncertain Data

Create an ensemble from an uncertainty and AR1 estimate

Description

Create an ensemble from an uncertainty and AR1 estimate

Usage

generateEnsembleFromUncertainty(
  variable,
  n.ens,
  sd,
  ar = sqrt(0.5),
  arima.order = c(1, 0, 0)
)

Arguments

variable	LiPD variable object or vector of data
n.ens	Number of ensemble members to create (default = 1000)
sd	Standard deviation of the uncertainty to simulate
ar	Autocorrelation coefficient to use for modelling uncertainty, what fraction of the uncertainties are autocorrelated? (default = sqrt(0.5); or 50 percent autocorrelated uncertainty)
arima.order	Order to use for ARIMA model used in modelling uncertainty (default = c(1,0,0))

Value

a matrix of ensemble values
