**pyextremes** is a Python library aimed at performing univariate
[Extreme Value Analysis (EVA)](https://en.wikipedia.org/wiki/Extreme_value_theory).
It provides tools necessary to perform a wide range of tasks required to
perform EVA, such as:
- extraction of extreme events from time series using methods such as
Block Maxima (BM) or Peaks Over Threshold (POT)
- fitting continuous distributions, such as GEVD, GPD, or user-specified
continous distributions to the extracted extreme events
- visualization of model inputs, results, and goodness-of-fit statistics
- estimation of extreme events of given probability or return period
(e.g. 100-year event) and of corresponding confidence intervals
- tools assisting with model selection and tuning, such as selection of
block size in BM and threshold in POT

with Jupyter notebooks used to produce figures for this readme
and for the official documentation.

# Acknowledgements
I wanted to give kudos to [Jean Toilliez](https://github.com/jtoilliez) who has inspired me to develop this open-source project and who taught me a lot about the extreme value theory. Also big thanks to Max Larson who has introduced me to software development and statistics.
