ARIMA模型，用来对非平稳信号的功率谱估计，很有用！-ARIMA model, used for non-stationary signals in power spectrum estimation, very useful!

Arima model parameters

doarima.m MATLAB scr ipt to do an ARIMA(p,d,q) analysis where d is set but P and q can be vectors of values you want to try. It produces AIC and FPE (final prediction error) values for comparing models. The AIC is differ
