The discrete uniform distribution. There are two parametrizations of
this distribution. First is the probability distribution on an
inclusive interval {1, ..., n}. This is parametrized with n only,
where p_1, ..., p_n = 1/n. (`discreteUniform`

).

The second parametrizaton is the uniform distribution on {a, ..., b} with
probabilities p_a, ..., p_b = 1/(a-b+1). This is parametrized with
*a* and *b*. (`discreteUniformAB`

)

# Constructors

:: Int | Range |

-> DiscreteUniform |

Construct discrete uniform distribution on support {1, ..., n}.
Range *n* must be >0.

:: Int | Lower boundary (inclusive) |

-> Int | Upper boundary (inclusive) |

-> DiscreteUniform |

Construct discrete uniform distribution on support {a, ..., b}.

# Accessors

*a*, the lower bound of the support {a, ..., b}

rangeTo :: DiscreteUniform -> Int Source #

*b*, the upper bound of the support {a, ..., b}
