Distribution: A package to demonstrate a few statistical distributions

This tq010or-distribution package is a demo for a few statistical distributions.

Features

• Can sample from the distribution
• Can estimate distribution parameters with samples
• Easy plot integration
• Support Gaussian and Binomial (as of July 2020)
• Extensible to include other distributions

Installation

• Operating system: Linux · Windows (Cygwin, MinGW, Visual Studio)
• Python version: Python 3.6+

pip

pip install tq010or-distribution

Or you can install them in your virtual environment:

python -m venv .env
source .env/bin/activate
pip install tq010or-distribution

Usage

>>> from distributions.gaussian import Gaussian
>>> g = Gaussian(0, 1)
>>> print(g)
Gaussian(0, 1)
>>> samples = g.sample(10000)
>>> ge = Gaussian.estimate(samples)
>>> print(ge)
Gaussian(0.016869274639641572, 0.9910041611791893)
>>> g1 = Gaussian(0, 3)
>>> g2 = Gaussian(1, 4)
>>> g3 = g1 + g2
>>> assert g3 == g1 + g2
>>>
