NewCategorical constructs a new categorical distribution where the probability that x equals i is proportional to w[i].

UnitNormal is an instantiation of the normal distribution with Mu = 0 and Sigma = 1.

UnitUniform is an instantiation of the uniform distribution with Min = 0 and Max = 1.

Bernoulli represents a random variable whose value is 1 with probability p and value of zero with probability 1-P.

Beta implements the Beta distribution, a two-parameter continuous distribution with support between 0 and 1.

Categorical is an extension of the Bernouilli distribution where x takes values {0, 1, ..., len(w)-1} where w is the weight vector.

ChiSquared implements the χ² distribution, a one parameter distribution with support on the positive numbers.

Exponential represents the exponential distribution (https://en.wikipedia.org/wiki/Exponential_distribution).

F implements the F-distribution, a two-parameter continuous distribution with support over the positive real numbers.

Gamma implements the Gamma distribution, a two-parameter continuous distribution with support over the positive real numbers.
