Description
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 parametrization 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)
