  • The Committee believes that a successful implementation of the revised Framework will provide banks and supervisors with critical experience necessary to address such challenges. The Committee understands that the IRB approach represents a point on the continuum between purely regulatory measures of credit risk and an approach that builds more fully on internal credit risk models. In principle, further movements along that continuum are foreseeable, subject to an ability to address adequately concerns about reliability, comparability, validation, and competitive equity.......

  • The immediate reason for the creation of this book has been the advent of Basel II. This has forced many institutions with loan portfolios into building risk models, and, as a consequence, a need has arisen to have these models validated both internally and externally. What is surprising is that there is very little written that could guide consultants in carrying out these validations. This book aims to fill that gap.

  • Food safety is of great importance to consumers. To ensure the safety of the food supply and to facilitate international trade, government agencies and international bodies establish standards, guidelines, and regulations that food producers and trade partners need to meet, respect, and follow. A primary goal of national and international regulatory frameworks for the use of veterinary drugs, including antimicrobials, in food-producing animals is to ensure that authorized products are used in a manner that will not lead to non-compliance residues.

  • Validation of Communications Systems with SDL provides a clear practical guide to validating, by simulation, a telecom system modelled in SDL. SDL, the Specification and Description Language standardised by the International Telecommunication Union (ITU-T), is used to specify and develop complex systems such as GSM, GPRS, UMTS, IEEE 802.11 or Hiperlan. Since the downturn in the telecom industry, validating a system before its implementation has become mandatory to reduce costs.

  • Sources of Evidence: Clinical Trials and Registries The notion of learning from observation of patients is as old as medicine itself. Over the last 50 years, our understanding of how best to turn raw observation into useful evidence has evolved considerably. Case reports, personal anecdotal experience, and small single-center case series are now recognized as having severe limitations to validity and have no role in formulating modern standards of practice. The major tools used to develop reliable evidence consist of the randomized clinical trial and the large observational registry.

  • Among the valid contraindications applicable to all vaccines are a history of anaphylaxis or other serious allergic reactions to a vaccine or vaccine component and the presence of a moderate or severe illness, with or without fever. Infants who develop encephalopathy within 72 h of a dose of DTP or DTaP should not receive further doses; those who experience a "precaution" event should not normally receive further doses. Because of theoretical risks to the fetus, pregnant women should not receive MMR or varicella vaccine.

  • Evidence-Based Medicine The "art of medicine" is traditionally defined as a practice combining medical knowledge (including scientific evidence), intuition, and judgment in the care of patients (Chap. 1). Evidence-based medicine (EBM) updates this construct by placing a much-greater emphasis on the processes by which the clinician gains knowledge of the most up-to-date and relevant clinical research. The key processes of EBM can be summarized in four steps: 1. Formulating the management question to be answered 2.

  • The third model is constructed by CIBC, following their usual data mining procedure for a direct marketing campaign. The modeller at CIBC trained the model, and then passed on to us the validation result. The supervised learning algorithm of their choice is linear logistic regression. A considerable amount of time is spent on data preparation, including variable selection, variable transformation, and variable imputation. The first step in their modelling procedure is to significantly reduce the number of input variables by performing exploratory analysis on the data.
