Syntax: Bet(shape1, shape2, minimum, maximum, stream)
The beta distribution (continuous) could be used to model the time required to perform some task when the possible values are restricted to the finite interval [minimum, maximum] (minimum >= 0.0, maximum >= 1.0, and maximum > minimum). Parameter restrictions for shape1 and shape2 are shape1 >= 0.0 and shape2 > 0.0. The density function is skewed to the left, symmetric, or skewed to the right if shape1 > shape2, shape1 = shape2, or shape1 < shape2, respectively. A beta distribution with shape1 = shape2 = 1 is a uniform distribution with the interval [0, 1].
Stream allows you to specify the random number stream for the distribution. There are 215 streams. Stream 1 is the default. See Seeds or Appendix D of the User's Guide for more information.
