case class Dice(cdf: Array[Double] = Array (.1, .3, .5, .7, .9, 1.0), stream: Int = 0) extends Variate with Product with Serializable

This class generates Dice random variates for a given distribution specified using a cumulative distribution function (cdf). This discrete RV models the roll of dice numbered 0, 1, ..., n-1. Add 1 for 1 to n.

cdf

the distribution function (cdf)

stream

the random number stream
