========
Overview
========



A module for calculation of PCA and PLS with the NIPALS algorithm. Based on the R packages
`nipals <https://cran.r-project.org/package=nipals>`_ and
`pcaMethods <https://doi.org/10.18129/B9.bioc.pcaMethods>`_ as well as the
statistical appendixes to "Introduction to Multi- and Megavariate Data Analysis
using Projection Methods (PCA & PLS)" by Eriksson et. al.
Tested to give same results as the above packages and Simca, with some rounding errors.

Installation
============

::

    pip install nipals

Documentation
=============

See https://github.com/fredrikw/python-nipals/blob/master/docs/nipals_demo_iris.ipynb
for an example and the tests at https://github.com/fredrikw/python-nipals/tree/master/tests.


Development
===========

To run the all tests run::

    tox

Note, to combine the coverage data from all the tox environments run:

.. list-table::
    :widths: 10 90
    :stub-columns: 1

    - - Windows
      - ::

            set PYTEST_ADDOPTS=--cov-append
            tox

    - - Other
      - ::

            PYTEST_ADDOPTS=--cov-append tox
