                  Here,      standard  backward  operator,   and      on  the  variable     with  polynomials


               integrated orders    and   seasonal avtoregressive       and moving average (     ).


                             th order avtoregression term can be noted as follows:


                                                                                                                       (8)


                                            th order moving average term can be noted as follows:


                                                                                                                       (9)


                                      th order seasonal avtoregression terms are as follows:



                                                                                                                    (10)


                                th order seasonal moving average terms are formulated as follows:


                                                                                                                    (11)



                   number of periods in the season.                 order difference     . This can be named


               as integrated order.                 order seasonal difference      .

                       b. Data


                        The data used in this study  were obtained from the statistics bulletin of Central Bank of

               Azerbaijan[10].The data covers the period starting from 2009 until 2014 on monthly basis.


                       3. Implementation of  SARIMA  and ARIMA models and results of the models.

                     Models  show  that  the  diagnostic  results  of  the  model    such  as  -  LM  test,  ARCH  test,


               normality test become statistical significant. Wheraas White test was statistical insignificant.
