Extreme Value Theory

Notes on rare-event modelling, block maxima, threshold exceedances, generalized extreme value limits, generalized Pareto models, tail index estimation, and extreme quantile inference.

Extreme Value Theory

Notes and drafts.

This section collects notes on statistical modelling of rare and extreme events. The focus is on the mathematical structure of tail limits and their use in risk, reliability, environmental extremes, and machine-learning-adjacent tail estimation.

Introduction to Extreme Value Theory

Draft note / EVT

A conceptual introduction to why extremes require separate asymptotic modelling, with block maxima and threshold exceedance viewpoints.

Generalized Pareto Distribution

Planned note

A note on threshold exceedances, the Pickands-Balkema-de Haan theorem, and tail modelling with the generalized Pareto distribution.

Extreme Quantile Estimation

Planned note

A note on estimating quantiles beyond the range of ordinary data and why extrapolation requires tail assumptions.
