To select input variables for use by the SAS/ETS Model Editor and add them to the Variable and Parameter Definitions list, select Parameters and Variables in the left pane of the model window. To specify equations to use in the model, select Equations in the left pane.

The right pane has the following controls and fields:

Equation:

enables you to enter the equations for the model.

Variable and Parameter Definitions

displays the variable and parameter definitions for the equations for the model that are shown in the Equation field. To add a new row, click the Add button . A new entry appears in the Variable and Parameter Definitions table. To edit the values for each entry, double-click the appropriate cell in the Variable and Parameter Definitions table. To delete an entry, select an existing entry and then click the Delete button .

Name column

specifies the name of the variable or parameter.

Type column

specifies the variable type. To change the type, click the down arrow and then select from the resulting list.

Label column

specifies the label of the variable or parameter.

Instrument? column

specifies whether the variable or parameter is an instrument. To change the value, click the down arrow and select from the resulting list.

Output To Data Set column

specifies the set of data set options for displaying output and saving it to a data set. To change the value, click the down arrow and select from the resulting list.

All dependent variables are instruments.

specifies whether all dependent variables are instruments.

Instruments Only Use Intercept.

specifies whether instruments only use an intercept.

Instruments Includes Intercept.

specifies whether the instruments include an intercept.

ID

specifies the ID variable. To change the value, click the down arrow and select from the resulting list.

Range:

specifies the time range between observations in the data set. Select a range from list.

Start:

specifies the starting date for the time series in the data set. Enter a date value in this field, using a form that is recognizable as a SAS date informat (for example, 1998:1, feb1997, or 03mar1998).

End:

specifies the ending date for the time series in the data set. Enter a date value in this field, using a form that is recognizable as a SAS date informat (for example, 1998:1, feb1997, or 03mar1998).
