pyextremes is a Python library aimed at performing univariateExtreme Value Analysis (EVA).It provides tools necessary to perform a wide range of tasks required toperform EVA, such as:

  • extraction of extreme events from time series using methods such asBlock Maxima (BM) or Peaks Over Threshold (POT)
  • fitting continuous distributions, such as GEVD, GPD, or user-specifiedcontinous 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 ofblock size in BM and threshold in POT

Acknowledgements

I wanted to give kudos toJean Toilliez 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.
