Defining Vectors Using Stochastic Elements

In addition to using Data elements to create vectors, you can also create vectors using Stochastic elements. If you define a Stochastic element as a vector, rather than inputting a single probability distribution, you specify a set of probability distributions (one for each item of the vector).

If you specify the Stochastic as a vector (by specifying a set of array labels via the Type… button), the dialog for defining the distribution (accessed via the Edit Distribution… button) will look similar to this:

All the inputs to the Stochastic must be vectors.
