Statistical correction and bias adjustment tools for xarray.

* Free software: Apache Software License 2.0
* Documentation: https://xsdba.readthedocs.io.

Features
--------

* The `xsdba` submodule provides a collection of bias-adjustment methods meant to correct for systematic biases found in climate model simulations relative to observations.
  Almost all adjustment algorithms conform to the `train` - `adjust` scheme, meaning that adjustment factors are first estimated on training data sets, then applied in a distinct step to the data to be adjusted.
  Given a reference time series (`ref`), historical simulations (`hist`) and simulations to be adjusted (`sim`), any bias-adjustment method would be applied by first estimating the adjustment factors between the historical simulation and the observation series, and then applying these factors to `sim``, which could be a future simulation:

* Time grouping (months, day of year, season) can be done within bias adjustment methods.

* Properties and measures utilities can be used to assess the quality of adjustments.

Quick Install
-------------
`xsdba` can be installed from PyPI:

.. code-block:: shell

    $ pip install xsdba

Documentation
-------------
The official documentation is at https://xsdba.readthedocs.io/

How to make the most of `xsdba`: `Basic Usage Examples`_ and `In-Depth Examples`_.

`xsdba` was first developed as the submodule `sdba` of `xclim`_. A `migration guide`_  is available for users of `sdba`.
