Discrete Uniform
Extends from Var (prototype for variate generation functions).
Information
DiscreteUniform
Discrete Uniform probability distribution.
Syntax
DiscreteUniform(g,i,j)
Description
Generates a random variate following the Discrete Uniform probability distribution in the interval [i,j].
The pseudo-code algorithm used for this distribution is:
1. Generate u as U(0,1).
2. Return x = i + floor((j - i + 1)*u)
Examples
(u,g) := DiscreteUniform(g,2,4);

| Real | a (from Var) | 0 | First parameter of the prob. distribution |
| Real | b (from Var) | 0 | Second parameter of the prob. distribution |
| Real | c (from Var) | 0 | Third parameter of the prob. distribution (only for the Johnson and Triangular distributions) |
