Exercises and Solutions in Statistical Theory

Exercises and Solutions in Statistical Theory helps students and scientists obtain an in-depth understanding of statistical theory by working on and reviewing solutions to interesting and challenging exercises of practical importance. Unlike similar books, this text incorporates many exercises that apply to real-world settings and provides much more thorough solutions.The exercises and selected detailed solutions cover from basic probability theory through to the theory of statistical inference. Many of the exercises deal with important, real-life scenarios in areas such as medicine, epidemiology, actuarial science, social science, engineering, physics, chemistry, biology, environmental health, and sports. Several exercises illustrate the utility of study design strategies, sampling from finite populations, maximum likelihood, asymptotic theory, latent class analysis, conditional inference, regression analysis, generalized linear models, Bayesian analysis, and other statistical topics. The book also contains references to published books and articles that offer more information about the statistical concepts.Designed as a supplement for advanced undergraduate and graduate courses, this text is a valuable source of classroom examples, homework problems, and examination questions. It is also useful for scientists interested in enhancing or refreshing their theoretical statistical skills. The book improves readers comprehension of the principles of statistical theory and helps them see how the principles can be used in practice. By mastering the theoretical statistical strategies necessary to solve the exercises, readers will be prepared to successfully study even higher-level statistical theory.

Making IT Lean: Applying Lean Practices to the Work of IT presents Lean concepts and techniques for improving processes and eliminating waste in IT operations and IT Service Management, in a manner that is easy to understand. The authors provide a context for discussing several areas of application within this domain, allowing you to quickly gain insight into IT processes and Lean principles.The text reviews IT Service Management, with reference to the IT Infrastructure Library (ITIL ) as a framework for best practices explaining how to use it to accommodate Lean processes and operations. Filled with straightforward examples, it provides enough modeling tools so you can start your Lean journey right away. Examining the work of IT from an IT practitioner perspective, the book includes coverage of:The OM Perspective considers the work of IT from an Operations Management (OM) perspective, showing how many of the concepts that have been successfully applied within manufacturing can be applied to ITThe Lean Improvement Model explains Lean concepts and practices and details the authors Lean improvement modelLean Problem-Solving (Identifying and Understanding Problems) considers operational work in IT and explains how to apply Lean practices related to problem identification and root cause analysisLean Problem-Solving (Identifying and Managing Solutions) describes how to use good problem identification as the basis for identifying the right solutionsLean IT Service Management examines IT work from an IT Service Management perspective, using the ITIL framework as a guideImplementing and Sustaining Lean IT Improvements explains how to implement and sustain Lean IT improvementsThroughout the book, the authors use a simple model for Lean Improvement as the framework
