Coherent Stress Testing: A Bayesian Approach to the Analysis of Financial Stress
A Bayesian Approachindustry expert Riccardo Rebonato presents a groundbreaking new approach to this important but often undervalued part of the risk management toolkit. Marginal and Conditional Probabilities. Volatility and Correlation Riccardo Rebonato Inbunden. Here Rebonato suggests some ways of combining “top down” approaches driven by macroeconomic structural risks with “bottom up” approaches driven by trading book risks. Ranjan marked it as to-read Jul 02, I Data, Cohedent and Reality.
Briefly, Rebona I read this one “because of” work although not “for” work. Even simple attempts to estimate such conditional probabilities can easily produce incoherent debonato logically incompatible — results. The mathematics at the core of this voherent intimidating at first glance, but is actually trivial — Venn diagrams, elementary probability, simple formalism — with some linear programming consigned to an appendix.
This is an entirely peripheral concern, however.
Rebonato concludes with some practical concerns. I certainly hope the risk managers at my banks understand Rebonato’s ideas. Volatility and Correlation Riccardo Rebonato.

Refresh and try again. October External links: Lists with This Book. Based on the author’s extensive work, research and presentations in the area, the book fills a gap in quantitative risk management by introducing a new and very intuitively appealing approach to stress testing based on expert judgement and Bayesian networks.
This is very different from the standard approach to stress testing, and I think it is really valuable to have people developing a diverse set of ideas about how one might go about the process.
Rebonato makes no attempt to use macroeconomic theory here, perhaps unsurprisingly given how primitive that is.
Perhaps the most difficult part of stress testing is the selection of stress scenarios. Stress testing is positioned as a bridge between the statistical areas where VaR can be effective and the domain of total Keynesian uncertainty.

It turns out that having only some marginal probabilities puts significant bounds on the joint probabilities, and having some singly conditioned probabilities makes those bounds tighter.
Part III takes readers through the application of the tools discussed in part II, and introduces two different systematic approaches to obtaining a coherent stress testing output that can satisfy the needs of industry users and regulators.
