``uravu`` (from the Tamil for relationship) is about the relationship between some data and a function that may be used to describe the data.

The aim of ``uravu`` is to make using the **amazing** Bayesian inference libraries that are available in Python as easy as [`scipy.optimize.curve_fit`](https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.curve_fit.html).
Therefore enabling many more to make use of these exciting tools and powerful libraries.
Plus, we have some nice plotting functionalities available in the `plotting` module, capable of generating publication quality figures.

In an effort to make the ``uravu`` API friendly to those new to Bayesian inference, ``uravu`` is *opinionated*, making assumptions about priors among other things.
However, we have endevoured to make it straightforward to ignore these opinions.

In addition to the library and API, we also have some [basic tutorials](https://uravu.readthedocs.io/en/latest/tutorials.html) discussing how Bayesian inference methods can be used in the analysis of data.

## Bayesian inference in Python

There are a couple of fantastic Bayesian inference libraries available in Python that `uravu` makes use of:

- [emcee](https://emcee.readthedocs.io/): enables the use of the [Goodman & Weare’s Affine Invariant Markov chain Monte Carlo (MCMC) Ensemble sampler](https://doi.org/10.2140/camcos.2010.5.65) to evaluate the structure of the model parameter posterior distributions,
- [dynesty](https://dynesty.readthedocs.io/): implements the [nested sampling](https://doi.org/10.1063/1.1835238) algorithm for evidence estimation.

## Problems

If you discover any issues with `uravu` please feel free to submit an issue to our issue tracker on [Github](https://github.com/arm61/uravu).
Alternatively, if you are feeling confident, fix the bug yourself and make a pull request to the main codebase (be sure to check out our [contributing guidelines](https://github.com/arm61/uravu/blob/master/CONTRIBUTING.md) first).

## Installation

`uravu` is available from the [PyPI](https://pypi.org/project/uravu/) repository so can be [installed using `pip`](https://uravu.readthedocs.io/en/latest/installation.html) or alternatively `clone` this repository and install the latest development build with the commands below.

```
pip install -r requirements.txt
python setup.py build
python setup.py install
pytest
```
