9. Model Inputs

Quantities must be included in a model in order to analyze the model. Some of the quantities you can enter in models are:

• Payoffs/rewards

• Probabilities

• Variable definitions

• Distribution parameters

• Function arguments

Although these quantities can be entered as simple numbers, TreeAge Pro allows the entry of numeric expressions, consisting of any or all of the following elements:

• Numbers

• Variables

• Table lookups

• Distributions

• Functions

• Operators

• Keywords

There are different reasons to use specific elements within an expression. This section focuses on how to create model inputs from a variety of these elements.
