This book takes a fresh look at the popular and well-established method of maximum likelihood for statistical estimation and inference. It begins with an intuitive introduction to the concepts and background of likelihood, and moves through to the latest developments in maximum likelihood methodology, including general latent variable models and new material for the practical implementation of integrated likelihood using the free ADMB software. Fundamental issues of statistical inference are also examined, with a presentation of some of the philosophical debates underlying the choice of statistical paradigm. Key features: Provides an accessible introduction to pragmatic maximum likelihood modelling. Covers more advanced topics, including general forms of latent variable models (including non-linear and non-normal mixed-effects and state-space models) and the use of maximum likelihood variants, such as estimating equations, conditional likelihood, restricted likelihood and integrated likelihood. Adopts a practical approach, with a focus on providing the relevant tools required by researchers and practitioners who collect and analyze real data. Presents numerous examples and case studies across a wide range of applications including medicine, biology and ecology. Features applications from a range of disciplines, with implementation in R, SAS and/or ADMB. Provides all program code and software extensions on a supporting website. Confines supporting theory to the final chapters to maintain a readable and pragmatic focus of the preceding chapters. This book is not just an accessible and practical text about maximum likelihood, it is a comprehensive guide to modern maximum likelihood estimation and inference. It will be of interest to readers of all levels, from novice to expert. It will be of great benefit to researchers, and to students of statistics from senior undergraduate to graduate level. For use as a course text, exercises are provided at the end of each chapter. Получить ссылку |
Mivar NETs and logical inference with the linear complexity
Автор: Олег Варламов
Год издания:
MIVAR: Transition from Productions to Bipartite Graphs MIVAR Nets and Practical Realization of Automated Constructor of Algorithms Handling More than Three Million Production Rules. The theoretical transition from the graphs of production systems to the bipartite graphs of the MIVAR nets is shown. Examples of the implementation of the MIVAR nets in the formalisms of matrixes and graphs are given. The linear computational complexity of algorithms for automated building of objects and rules of the MIVAR nets is theoretically proved. On the basis of the MIVAR nets the UDAV software complex is developed, handling more than 1.17 million objects and more than 3.5 million rules on ordinary computers. The results of experiments that confirm a linear computational complexity of the MIVAR method of information processing are given.
Managing to Make a Difference. How to Engage, Retain, and Develop Talent for Maximum Performance
Автор: Larry Sternberg
Год издания:
A practical, real-world training manual for mid-level management Managing to Make a Difference presents a leadership guide for those in the middle. The C-suite has a wealth of resources for leadership guidance, but middle managers face a quandary: often given little guidance on how to excel, they are also under enormous pressure to do a variety of things other than «lead.» This book provides much-needed tools and techniques for building a high-performing team—without letting your other duties suffer. Organized around a coherent philosophy and based on solid research, the discussion offers a roadmap to engagement, talent development, and excellence in management. From difficult situations and organizational challenges to everyday motivation and inspiration, these techniques help middle managers achieve the goals of their organization while empowering their workers to achieve their own. Talent development is probably not your full-time job—yet it drives the engagement that results in high performance. This book shows you how to hit the «sweet spot» of middle management, with a host of tools and strategies to help you help your team shine. Motivate, inspire, and lead your team with confidence Manage through challenges and overcome obstacles Develop key talent and maintain high engagement Adopt practical management tools based on substantiated research Most organizations direct the majority of their development resources to the C-suite, but still expect their mid-level managers to attract, engage, retain, and develop talent; but successfully juggling everyday duties while maintaining team performance and leading around roadblocks leaves little room for management planning. Managing to Make a Difference offers the solution in the form of tools, techniques, and practical strategy for a high performing team.

Trend Trading Set-Ups. Entering and Exiting Trends for Maximum Profit
Автор: L. A. Little
Год издания:
An expert reveals a step-by-step process for profiting from neoclassical qualified trend trading Trend Trading Set-Ups extends the neoclassical concept of qualified trend first introduced by Little in Trend Qualification and Trading, providing traders and investors with a sound methodology for uncovering the very best trade set-ups and the ability to time trade entries like never before. In Trend Trading Set-Ups, Little reveals the data behind qualified trends and utilizes a novel concept involving time to calculate trend failure probability rates. Little reduces the complex to its most simplistic form compressing all trades types into just two classes – retraces and breakouts. Once simplified, over a decade worth of qualified trend data is examined. The result is a comprehensive presentation of what makes some trades enormously better than others and how you can both find and exploit the most favorable trade set-ups. Some trading books are an interesting read but soon forgotten. A few books you place on the reachable shelf and refer to often. In Trend Trading Set-Ups L.A. Little offers you an entirely new way of approaching an old subject and does so in a style that is both as riveting as it is valuable. As with Trend Qualification and Trading you will find this book an easy but comprehensive read and one that you will turn to again and again while pursuing your trading and investing endeavors.
Information-Driven Business. How to Manage Data and Information for Maximum Advantage
Автор: Robert Hillard
Год издания:
Information doesn't just provide a window on the business, increasingly it is the business. The global economy is moving from products to services which are described almost entirely electronically. Even those businesses that are traditionally associated with making things are less concerned with managing the manufacturing process (which is largely outsourced) than they are with maintaining their intellectual property. Information-Driven Business helps you to understand this change and find the value in your data. Hillard explains techniques that organizations can use and how businesses can apply them immediately. For example, simple changes to the way data is described will let staff support their customers much more quickly; and two simple measures let executives know whether they will be able to use the content of a database before it is even built. This book provides the foundation on which analytical and data rich organizations can be created. Innovative and revealing, this book provides a robust description of Information Management theory and how you can pragmatically apply it to real business problems, with almost instant benefits. Information-Driven Business comprehensively tackles the challenge of managing information, starting with why information has become important and how it is encoded, through to how to measure its use.
