uniform (Discrete)
Generates random numbers uniformly distributed over the interval [a, b).
Description
The uniform class object is used in generate functions to provide random numbers uniformly distributed over the interval [a, b), where a, b are the left and right bounds of the interval respectively, and .
The probability distribution is given by:
