Document description

The extreme events working party has developed an open-source excel tool to fit extreme value (GPD) distributions to historic data sets. This workshop demonstrates:

  • how to understand estimation error by using the tool on simulated data
  • how to make good choices for the configuration settings
  • estimated 99.5 percentiles from equity and interest data, compared to the results of alternative fitting approaches.
