Assigning Data to Roles

To run the Modeling and Forecasting task, you must select an input data source. To filter the input data source, click Filter Icon

You must assign a column to the Dependent variable role, and you must specify a forecasting model type on the Model tab.

Roles and Options	Description
Roles
Dependent variable	specifies the dependent variable.
Additional Roles
Time ID	specifies the column that contains the time ID values.
Properties
Interval	shows the interval for the time ID variable. For more information about SAS time intervals, see Understanding SAS Time Intervals. Note: This value is determined by the input data set. You cannot change this value in the Modeling and Forecasting task.
Multiplier	shows the multiplier for the time interval. By default, the multiplier is 1. Note: This value is determined by the input data set. You cannot change this value in the Modeling and Forecasting task.
Shift	shows the shift for the time interval. By default, the shift is 1. Note: This value is determined by the input data set. You cannot change this value in the Modeling and Forecasting task.
Season length	specifies the seasonality of the time interval. The default value depends on the time interval.
Additional Roles
Season length	enables you to specify the seasonality of the data when you do not assign a time ID variable.
Group analysis by	enables you to obtain separate analyses of observations for each unique group.
