# Student's t-Mixture Model

A Python implementation of "Robust mixture modelling using the t distribution" (Peel & McLachlan, 2000) and extensions.

# Features
* Class StudentMixture: module for fitting a mixture of multivariate Student's t-distributions.
* Class MultivariateT: module for using a multivariate Student's t-random variable
* Class MultivaraiteTFit: module for fitting a multivariate Student's t-distribution. 

# Installation
With pip:
```
pip install student-mixture
```
From github:
```
git clone https://github.com/omritomer/student_mixture.git
cd student_mixture
python setup.py build
python setup.py install
```

# Requirements
* numpy==1.17.3
* scipy==1.3.1
* scikit-learn==0.21.3
