K is the total number of models, AICk is the AIC value for model k, and BestAIC is the AIC value for the model with the minimum AIC value.
Model Comparison Table
You can select which full model reports are shown in the report window using the Report checkbox. Two model plots appear to the right of the Model Comparison table. The top plot is a time series plot of the data, forecasts, and prediction limits. Below that are plots of the autocorrelation and partial autocorrelation functions. You can select which models are displayed on the model plots using the Graph checkbox.
Model Plots
Provides one simulation of the model out k time periods. The simulation is shown on the Model Comparison time series plot. To change k, use the Number of Forecast Periods option in the Time Series red triangle menu.
Provides the specified number of simulations of the model out k time periods. The simulations are shown on the Model Comparison time series plot. To change k, use the Number of Forecast Periods option in the Time Series red triangle menu.
