case class DiscreteF(f: Array[FunctionS2S] = Array ((x: Double) => x), stream: Int = 0) extends Variate with Product with Serializable
The DiscreteF class generates generalized Discrete random variates for a
distribution specified via an array of functions (FunctionS2S). At a
particular time 't', the functions must some to one.
This discrete RV models time-varying experiments with discrete outcomes.
