Dist

A Haskell library for probability distributions

This library provides a data structure and associated functions for representing discrete probability distributions.

This library is optimized for very fast sampling. If n is the number of unique outcomes, sampling from the distribution is O(log(n)) worst case, and O(1) best case.

The average time complexity depends on the distribution. A more evenly distributed distribution will be closer to O(log(n)). A less evenly dsitributed distribution will be closer to O(1).
