distributions

An assortment of probability distributions.

Note that these implementations do not necessarily use the same parametrization as the corresponding implementations in scipy.stats.

Utility classes

Initial(initial)

This class allows an initial guess of a parameter to be passed to the mle function of a probability distribution.
