Deriving a formula from an ARIMAX model

    Hello all,

    I am finishing my master thesis and have included an ARIMAX model in the research. Now I would like to make some manual calculations based on the results from the ARIMAX Model in SPSS. I know that the results are not all significant but this is not a concern because a simulated example is used so the significance is not that important.

    My question, for now, is how to derive a formula from this model (and which formula to use), and to use the results of the model in SPSS to make some manual calculations for future values of revenue.

    Does anyone know a solution for this? Suggestions would be greatly appreciated!

    When you estimate the model, you can save it as an xml file.  Then you can apply that to new data using the Scoring Wizard on the Utilities menu.
