[A convenient way for autoregressive moving average model order determination: autoregressive moving average (n, n-1) modeling strategy].

ABSTRACT

OBJECTIVE: To introduce the autoregressive moving average (ARMA)(n, n-1) modeling strategy as to a convenient way for the determination of ARMA orders. METHODS: ARMA(n, n-1) strategy was generally explained. A simulated ARMA(3,2) time series was generated and analized following this strategy. RESULTS: Combined with AIC information criteria and residue plot, the order of ARMA model was determined and complied well with the simulated data. CONCLUSION: ARMA(n, n-1) strategy may be convenient for the medical workers.
