This function calls arima.sim but with more simple parameter structure for stationary ARIMA (or ARMA) models
gen.arima.wge(n, phi=0, theta=0, d=0,s=0,mu=0,vara=1,plot=TRUE,sn=0)
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 |
This function simply generates and (optionally plots) an ARIMA (or ARMA) realization
