In walkerjeffd/weathergen: Daily weather generator for performing a climate stress test.

Simulate Annual Timeseries with ARIMA Model

Description

Fit an ARIMA model to a given vector of annual precipitation x, and run a simulation of length n_year beginning with year start_year.

Usage

sim_annual_arima(x, start_year = 2000, n_year = 10)

Arguments

x	vector of observed annual values
start_year	first simulation year
n_year	number of simulation years

Value

a named list containing:

model	the fitted arima model returned by forecast::auto.arima()
x	the historical annual precipitation as a numeric vector
out	the simulated annual precipitation of length n_year as a zoo object

Examples

sim_annual_arima(rnorm(100))
