Examining Models

Once you have estimated a model, you need to investigate its properties. You have to simulate it, test its predictions, and compute its poles and zeros and so on. You thus have to transform the model to various ways of representing and presenting it. This section deals with how this is done. The following topics will be covered:

• Parametric models: basic use, accessing properties, simulation and prediction. Also manipulating channels, in particular the noise input channels.
• Frequency domain models
• Graphing model properties
• Transformations to other representations
• Transformations between continuous and discrete time
