Kumaraswamy

A simple implementation of the Kumaraswamy distribution.

How to use

Install it from pip (kumaraswamy only depends on numpy)

pip install kumaraswamy

and it's ready to use from Python

import kumaraswamy

The package provides one simple class called kumaraswamy, which implements the distribution. It is intended to mimic the API of scipy.stats.

from kumaraswamy import kumaraswamy

d1 = kumaraswamy(a=0.5, b=0.5)

the d1 object now has methods

• pdf(x) and logpdf(x)
• cdf(x)
• rvs(size)

to calculate the probability density function (and its logarithm), the cumulative density function, and to get random samples from the distribution.

Also available are some basic properties specific to the distribution

d1.mean
d1.var
d2.mode  # see help(d2.mode) for details
