distribution
is a package for manipulating finite discrete probability distributions.
It supports transformations of distributions, measurements and efficient sampling.
Plotting distributions as bar charts is also possible using the related distribution-plot
package.
The distribution
package contains several modules:
Data.Distribution.Core
which defines distributions and combinators over distributions,Data.Distribution.Measure
which includes measures such as probability, expectation and variance,Data.Distribution.Sample
which implements Walker's Alias method for efficiently sampling random values from distributions.
In addition, some domain specific distributions and functions are proposed by default:
Data.Distribution.Domain.Dice
defines dice and functions on dice.Data.Distribution.Domain.Coin
defines the same for coins.Data.Distribution.Aggregator
contains functions for transforming distributions to cumulative distributions and other useful methods.
Each module and each function is extensively documented.
See the distribution-plot
package for plotting distributions to files. This package is also available on GitHub.
