Coherent Stress Testing - Riccardo Rebonato - Bog - John Wiley & Sons Inc - Plusbog.dk

Coherent Stress Testing - Riccardo Rebonato - Bog - John Wiley & Sons Inc - Plusbog.dk

In Coherent Stress Testing: A Bayesian Approach , industry expert Riccardo Rebonato presents a groundbreaking new approach to this important but often undervalued part of the risk management toolkit. 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. It constitutes a radical departure from the traditional statistical methodologies based on Economic Capital or Extreme-Value-Theory approaches. The book is split into four parts. Part I looks at stress testing and at its role in modern risk management. It discusses the distinctions between risk and uncertainty, the different types of probability that are used in risk management today and for which tasks they are best used. Stress testing is positioned as a bridge between the statistical areas where VaR can be effective and the domain of total Keynesian uncertainty. Part II lays down the quantitative foundations for the concepts described in the rest of the book. 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. In part IV the author addresses more practical questions such as embedding the suggestions of the book into a viable governance structure.

Accelerated Life Testing of One-shot Devices - Narayanaswamy Balakrishnan - Bog - John Wiley & Sons Inc - Plusbog.dk

Accelerated Life Testing of One-shot Devices - Narayanaswamy Balakrishnan - Bog - John Wiley & Sons Inc - Plusbog.dk

Provides authoritative guidance on statistical analysis techniques and inferential methods for one-shot device life-testing Estimating the reliability of one-shot devices—electro-expolsive devices, fire extinguishers, automobile airbags, and other units that perform their function only once—poses unique analytical challenges to conventional approaches. Due to how one-shot devices are censored, their precise failure times cannot be obtained from testing. The condition of a one-shot device can only be recorded at a specific inspection time, resulting in a lack of lifetime data collected in life-tests. Accelerated Life Testing of One-shot Devices: Data Collection and Analysis addresses the fundamental issues of statistical modeling based on data collected from accelerated life-tests of one-shot devices. The authors provide inferential methods and procedures for planning accelerated life-tests, and describe advanced statistical techniques to help reliability practitioners overcome estimation problems in the real world. Topics covered include likelihood inference, competing-risks models, one-shot devices with dependent components, model selection, and more. Enabling readers to apply the techniques to their own lifetime data and arrive at the most accurate inference possible, this practical resource: - - Provides expert guidance on comprehensive data analysis of one-shot devices under accelerated life-tests - - Discusses how to design experiments for data collection from efficient accelerated life-tests while conforming to budget constraints - - Helps readers develops optimal designs for constant-stress and step-stress accelerated life-tests, mainstream life-tests commonly used in reliability practice - - Includes R code in each chapter for readers to use in their own analyses of one-shot device testing data - - Features numerous case studies and practical examples throughout - - Highlights important issues, problems, and future research directions in reliability theory and practice - Accelerated Life Testing of One-shot Devices: Data Collection and Analysis is essential reading for graduate students, researchers, and engineers working on accelerated life testing data analysis.

Quantitative Reverse Stress Testing - Assad Bouayoun - Bog - John Wiley & Sons Inc - Plusbog.dk

Quantitative Reverse Stress Testing - Assad Bouayoun - Bog - John Wiley & Sons Inc - Plusbog.dk

A practioner’s guide to quantitative reverse stress testing, featuring advanced solutions for better management of financial risks Whether you manage a portfolio, a business unit or a bank, you must ensure that a sudden shock in the markets won’t drive you out of business because of a large loss, a jump in capital utilisation or an increase in funding consumption . In financial risk management, reverse stress testing is the attempt to identify worst case scenarios causing maximum financial loss. Traditional stress testing methods have failed to avert the last financial crisis or highlight financial distress. . Every so often some regulators and risk managers specify stress scenarios with simplifications that create a false sense of safety. To avoid a combinatorial explosion, a number of arbitrary choices are usually made in relation to the level of each shock, their combination and the time horizon. These assumptions, although necessary, limit the effectiveness of this technique. Quantitative Reverse Stress Testing: Hunting for the Black Swan offers a more natural approach to identifying the realistic scenario provoking the largest losses. It also provides a means to understand the impact of extreme events and how to mitigate them while introducing technological advances and the adapted mathematical tools that have made it possible to solve this type of quantitative finance problems. You’ll see how mitigation strategies can be more accurate and better targeted, reducing risk, cost of funding and regulatory capital. With this book, you’ll have access to a comprehensive guide to crucial aspects of reverse stress testing. · Get an introduction to a rigorous mathematical framework to quantitative reverse stress testing · Consider different heuristics, one of them based on annealing, to solve theoptimisation problem · Review solution implementation, system infrastructure design and integration into the financial risk management of a firm · Read related case studies from a variety of industries If it’s time to move your approach to reverse stress testing forward, this guide offers real solutions tooptimisation and cost issues. Get a guide that supports a more informed approach to testing and financial risk management as it helps to protect vital business interests.
