lmoments3 1.0.8

A library extend scipy with L-moments to calculate optimal parameters for a number of distributions

A Python3 library to estimate linear moments for statistical distribution functions.

Requires the packages numpy and scipy.

For the Python 2.x compatible package see lmoments on the Python Package Index.

Installation

lmoments3 can be installed via pip

$ pip install lmoments3

or, alternatively, you can install it from conda-forge:
