New Fitted Model Wizard

The New Fitted Model wizard provides a step-by-step interface that enables you to create and define the equation statements, variable definitions, parameter definitions, and constraints that can be used to fit many different market data sets. You can create a fitted model either from scratch or by modifying an existing model template. The following instructions walk you through creating a fitted model from an existing model template. To create a new fitted model from an existing model template, right-click a named model template in the SAS libraries panel, and then select New Fitted Model. The Fitted Model wizard opens.

The Fitted Model wizard sequentially asks you to provide the following information:

1. name of your model and the location where it is to be stored.

2. name of an existing input data set.

3. creation or verification of the formula for your model.

4. model parameters and variables.

5. mapping of the variables from the model template to the input data set variables if the fitted model is created using a model template.

6. name of any output data sets desired (optional).

7. configuration of the fit options (such as estimation methods and optimization settings) for the model.

After you have provided the preceding information, the new model is fitted against the supplied input data set, and the results and model are stored at the location specified. If the new fitted model is built from a model template, its content is similar to the template content with the following exceptions: the input and output data sets are defined and all of the model program variables are changed based on the variable mapping. After a fitted model is created, subsequent changes that are made to the model template from which it was created have no effect on the fitted model.

The lower part of each page in the Fitted Model wizard contains the following controls:

• Details provides the options for each step.

• SAS Code provides the SAS statements for the entire model.

• Back moves the wizard back to the previous page.

• Next moves the wizard forward to the next page.

• Finish saves the model and causes the model program to run and generate the statistical results.

• Cancel closes the wizard unconditionally, and nothing is saved.

• Help provides help about the wizard.

The following sections show the step-by-step process of the Fitted New Model wizards.
