# Metran

Metran is a package for performing multivariate timeseries analysis using a 
technique called dynamic factor modelling. It can be used to describe the 
variation among many variables in terms of a few underlying but unobserved 
variables called factors.

## Installation

To install Metran, a working version of Python 3.7 or 3.8 has to be installed on your computer. 
We recommend using the Anaconda Distribution with Python 3.8 as it includes most 
of the python package dependencies and the Jupyter Notebook software to run the 
notebooks. However, you are free to install any Python distribution you want.

To install `metran`, type the following command

`pip install metran`

To install in development mode, clone the repository and type the following from the module root directory:

`pip install -e .`

## Documentation

The docs can be viewed [here](https://metran.readthedocs.io/).

## Examples

For a brief introduction of the theory behind Metran on multivariate timeseries analysis with
dynamic factor modeling see the notebook:

-   [The Dynamic Factor Model](https://github.com/pastas/metran/blob/main/examples/dynamic_factor_model.ipynb)

A practical real-world example, as published in Stromingen (Van Geer, 2015), is given in the following notebook:

-   [Metran practical example](https://github.com/pastas/metran/blob/main/examples/metran_practical_example.ipynb)

A notebook on how to use [Pastas](https://github.com/pastas/pastas) models output with Metran:

not already available:

-   numpy>=1.16.5
-   pandas>=1.0
