Overview of SAS/ETS Model Editor

The SAS/ETS Model Editor enables you to interactively create and edit model templates and fitted models that are associated with econometric time series models and risk models. These models are developed from time series and cross-sectional data. You can use these models to statistically model market behavior.

The SAS/ETS Model Editor consists of the following:

• a fitted model wizard with which you can create and define the equation statements, variables and parameters, constraints, and fit options on a step-by-step basis. You can apply a fitted model to any specific market data.

• a program editor panel, which enables you to write programming code to define your model and create additional dialog boxes. The additional dialog boxes enable you to more explicity specify properties associated with your model.

• a model template which you can also create to define the equation statements, variables and parameters, and constraints that you need in the programming code. Model templates are commonly used models that can be applied to a wide variety of data.

You can use either the Fitted Model Wizard or a model template to fit the model to a specific market data set to generate the model parameter estimates and other statistical results as specified in the MODEL procedure. The MODEL procedure analyzes models in which the relationships among the variables comprise a system of one or more nonlinear equations. Primary uses of the MODEL procedure are estimation, simulation, and forecasting of nonlinear simultaneous equation models. See Chapter 18, "The MODEL Procedure" (SAS/ETS User’s Guide), for more information.This chapter provides a reference to the various windows of the SAS/ETS Model Editor. The windows are presented in work flow order. Each section describes the purpose of the window, how to open it, its controls, fields, and menus.
