Estimating Operational Risk Capital: the Challenges of Truncation, the Hazards of MLE, and the Promise of Robust Statistics

J.D. Opdyke and Alex Cavallo

In operational risk measurement, the estimation of severity distribution parameters is the main driver of capital estimates, yet this remains a non-trivial challenge for many reasons.  Maximum likelihood estimation (MLE) does not adequately meet this challenge because of its well-documented non-robustness to modest violations of idealized textbook model assumptions, specifically that the data are independent and identically distributed (i.i.d.), which is…

Course: Spatial Statistics With GIS

By Dr. David Unwin

Aim of Course:

For centuries, geographers have laboured to discover and document our planet. Along the way they have used a variety of analytical techniques and drawn a variety of different types of map, but, by and large, this work has been conducted in isolation, without significant impact on the worlds of other sciences, commerce and industry.

The world discovers "geography": With the development of computer-based…
