Manipulation of catastrophe model outputs, including
tasks such as simulating year loss tables (YLTs) from event loss tables (ELTs),
adjusting the frequencies of events in YLTs to create new YLTs,
applying catastrophe exceedance of loss contracts (catXL),
applying hours clauses,
and calculating diagnostics from ELTs and YLTs, such as average annual loss
and exceedance probability curves. Frequency adjustment routines are
based on the paper "A new simulation algorithm for
more precise estimates of change in catastrophe risk models, with application to
hurricanes and climate change", Jewson, S. (2023);
