CalTitle1: Symbolic data analysis for extremes

Statistics Seminar: Scott Scisson (UNSW) -- Symbolic data analysis for extremes
Abstract:
Symbolic data analysis (SDA) is an underdeveloped statistical method in which the
individual "data points" for analysis are themselves distributions. How to construct
and then analyse these "symbols" is an ongoing research problem. This talk will
briefly introduce the ideas behind SDA, before demonstrating how they can be used to
fit extreme value distributions with an arbitrarily large numbers of classical
observations. This procedure can be shown to offer one way to fit max-stable process
models using pairwise (or higher) composite-likelihoods with an arbitrarily large
number of spatial locations, which would otherwise be computationally prohibitive.
(Note: This talk was recently presented at an extreme value theory workshop, hence
the focus on extremes. The methods and ideas are broadly applicable however).
