title: [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.
  
  
  CONCLUSIONS
  ARMA(n, n-1) strategy may be convenient for the medical workers.
