Letting denote the mean and standard deviation of the time series values Z1, Z2 ,...., Zn，it follows（as in Chapter 9）that one very approximate procedure is to decide that Z_bar is statistically different from zero and thus to include the constant term  =  p(B) p (BL)in the general Box-Jenkins model if absolute value of CC is greater than 2. Moreover，in order to determine which of the operators p(B)，p (BL)，q(B)，and Q(BL) should be included in the general Box-Jenkins model，we do the following。
