Description: Analysis of typical time series model with ARMA (2,2) model, X (n)+0.3 X (n-1)-0.2X (n-2) = W (n)+0.5 W (n-1)-0.2 W (n-2) W (n) is zero mean normal white noise, variance of 4 (1) generated by MATLAB model X (n) of the 500 observation points, the sample function and the waveform (2) You generated an estimated 500 observation points X (n) the mean and variance (3) draw the theory of power spectrum (4) of the estimated X (n) of the correlation function and power spectrum
