gen.arima.wge: Function to generate an ARIMA (or ARMA) realization

Description

This function calls arima.sim but with more simple parameter structure for stationary ARIMA (or ARMA) models

Usage

gen.arima.wge(n, phi=0, theta=0, d=0,s=0,mu=0,vara=1,plot=TRUE,sn=0)

Value

This function simply generates and (optionally plots) an ARIMA (or ARMA) realization

Arguments

n

Length of realization to be generated

phi

Vector of AR coefficients

theta

Vector of MA coefficients

d

Order of the difference

s

Seasonal order

vara

White noise variance, default=1

mu

Theoretical mean of data in x, default=0

plot

Logical: TRUE=plot, FALSE=no plot

sn

determines the seed used in the simulation. sn=0 produces new/random realization each time. sn=positive integer produces same realization each time
