SimulateAR1 function

Simulate AR(1) series

An AR(1) series with mean zero and variance 1 and with autocorrelation paramater phi is simulated.

SimulateAR1(n, phi)

Arguments

• n: length of series
• phi: autocorrelation parameter

Details

The model equation is: z[t] = phi*z[t-1]+a[t], where z[1] is N(0,1) and a[t] are NID(0, siga), $siga=\sqrt(1/(1-phi^2))$.

Returns

autocorrelated time series of length n
