ARIMA vs. ARIMAX – which approach is better to analyze and

GARCH TIME SERIES PROCESS Econometrics 7590 Projects 2 and 3 Zsuzsanna HORVATH and Ryan JOHNSTON´ Abstract: We examine in detail the various attributes of a time series data set for fi-nancial returns. We consider multiple time series models in order to determine which will proved the best fit. Particular attention is placed on the mathematical properties of the most common models. Topic

Fit an ARIMA model to a time series in Excel XLSTAT

Consequently, we choose the ARIMA(0,1,3)(0,1,1) \(_4\) model. Its residuals are plotted in Figure 8.21 . All the spikes are now within the significance limits, so the residuals appear to be white noise.

Fitting an ARIMA(p,d,q) model into a time series is a matter of choosing the order p for the autoregressive parameters, the order q for the moving average parameter and the number d of differences to be applied in the time series.

We can assess how well the ARIMA (3,1,3) model fits our data by choosing Stat > Time Series > ARIMA and completing the dialog box as shown below: Minitab produces this output: The p values are only significant at the 10% level for the first-order coefficient of the autoregressive part of the model and the 3rd order coefficient of the moving average part of the model.

Also, in a more general sense, bear in mind that the order of your ARIMA may imply a structural form. For example an ARIMA(0,2,2) is the same as a local linear trend model. For example an ARIMA(0,2,2) is the same as a local linear trend model.
