The mathematics at the core of this looks intimidating at first glance, but is actually trivial — Venn diagrams, elementary probability, simple formalism — with some linear programming consigned to an appendix. Based on the author’s extensive work, research and presentationsin the area, the book fills a gap in quantitative risk managementby introducing a new and very intuitively appealin In Coherent Stress Testing: But it is a great strength of his approach that the relationship of the theoretical framework and its mathematics to the underlying modelling is always visible, and that the sensitivity of the conclusions to the assumptions and inputs is transparent.

A theoretical framework is illustrated with worked examples and accompanied by detailed advice on practical implementation. He also argues for a Bayesian view of probabilities, introduces the problems of tail co-dependence, and looks at what is involved in moving from associative to causal models.
