Estimators and analysis for extreme value theory (EVT)

Estimators and analysis for extreme value theory (EVT). The package is structured as follows. Example notebooks are provided as links.

• The Dataset object performs sanity-checks and contains plotting routines.
  • Generic plots of the dataset.
  • Maximum-to-sum plot.
  • Mean excess function.
• The peaks over threshold method.
  • Plot the tail.
  • QQ-plot against exponential.
  • Zipf-plot.
• The block maxima method.
  • Plot block maxima against the dataset.
• Estimators: calculate estimates and confidence intervals. Plotting routines for analysis.
  • Hill estimator. Plot against order statistics.
  • Moment estimator (Dekkers-Einmahl-De Haan). Plot against order statistics.
  • Maximum likelihood for the generalized Pareto distribution. Plot fit quality.
  • Maximum likelihood for the generalized extreme value distribution. Plot fit quality.

Installation

Releases are made available on PyPi. The recommended installation method is via pip:

pip install evt

For a development setup, the requirements are in dev-requirements.txt. Subsequently, the repo can be locally pip-installed.
