R no es solamente el programa estadístico de uso general más potente y versátil, además de ser totalmente gratuito, sino que es también el que tiene la mayor variedad y potencia de grá?cos. Los grá?cos son una forma de presentar la información de modo que pueda ser ade- cuadamente interpretada, y tradicionalmente acompaña a otros resultados estadísticos como medidas, tablas, modelos, contrastes, etc. Sin embargo, la evolución moderna de la ciencia estadística ha conducido a una situación en la cual los grá?cos ya no son solamente un complemento que ayuda a ver mejor los resultados, sino potentes herramientas de análisis, imprescindibles para el usuario avanzado. Los grá?cos son con frecuencia el resultado principal de la aplicación de una técnica estadística. Algunos han alcanzado un grado de complejidad tan elevado que su comprensión requiere un aprendizaje experto, y un conocimiento profundo de los principios estadísticos utilizados en su construcción para asegurar la correcta interpretación. En este libro se presentan en primer lugar las técnicas generales para la construcción de grá?cos en R, con numerosos ejemplos de aplicación que permitirán al lector utilizar las funciones básicas con soltura, y así poder sacar el mejor partido de R para la construcción de grá?cos personalizados. En la segunda parte del libro se revisan de forma sistemática los principales grá?cos, desde los más básicos y habituales (dispersión, histograma, diagrama de barras, de cajas, etc.) hasta los más complejos (biplot, curvas de nivel, grá?cos de control, grá?cos para meta-análisis, árboles de clasi?cación, mapas, etc.), incluyendo algunos grá?cos de reciente aparición asociados a técnicas estadísticas novedosas. En todos los casos se presentan con detalle los procedimientos para la construcción de los grá?cos y las principales claves de interpretación, de modo que puedan ser utilizados por usuarios no expertos o con conocimientos estadísticos básicos. Este libro quiere ser útil a todos aquellos (estudiantes, profesores, técnicos, investigadores, etc.) que necesitan las herramientas grá?cas en su trabajo, y también a los usuarios de la estadística que desean profundizar en el conocimiento y la utilización del programa estadístico

DON’T MISS BRIDGE OF CLAY, MARKUS ZUSAK’S FIRST NOVEL SINCE THE BOOK THIEF. The extraordinary #1 New York Times bestseller that is now a major motion picture, Markus Zusak's unforgettable story is about the ability of books to feed the soul. When Death has a story to tell, you listen. It is 1939. Nazi Germany. The country is holding its breath. Death has never been busier, and will become busier still. Liesel Meminger is a foster girl living outside of Munich, who scratches out a meager existence for herself by stealing when she encounters something she can’t resist–books. With the help of her accordion-playing foster father, she learns to read and shares her stolen books with her neighbors during bombing raids as well as with the Jewish man hidden in her basement. In superbly crafted writing that burns with intensity, award-winning author Markus Zusak, author of I Am the Messenger, has given us one of the most enduring stories of our time. “The kind of book that can be life-changing.” —The New York Times “Deserves a place on the same shelf with The Diary of a Young Girl by Anne Frank.” —USA Today

INSTANT NEW YORK TIMES BESTSELLER “One of the most important books I’ve ever read—an indispensable guide to thinking clearly about the world.” – Bill Gates “Hans Rosling tells the story of ‘the secret silent miracle of human progress’ as only he can. But Factfulness does much more than that. It also explains why progress is so often secret and silent and teaches readers how to see it clearly.” —Melinda Gates Factfulness: The stress-reducing habit of only carrying opinions for which you have strong supporting facts. When asked simple questions about global trends—what percentage of the world’s population live in poverty; why the world’s population is increasing; how many girls finish school—we systematically get the answers wrong. So wrong that a chimpanzee choosing answers at random will consistently outguess teachers, journalists, Nobel laureates, and investment bankers. In Factfulness, Professor of International Health and global TED phenomenon Hans Rosling, together with his two long-time collaborators, Anna and Ola, offers a radical new explanation of why this happens. They reveal the ten instincts that distort our perspective—from our tendency to divide the world into two camps (usually some version of us and them) to the way we consume media (where fear rules) to how we perceive progress (believing that most things are getting worse). Our problem is that we don’t know what we don’t know, and even our guesses are informed by unconscious and predictable biases. It turns out that the world, for all its imperfections, is in a much better state than we might think. That doesn’t mean there aren’t real concerns. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most. Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world and empower you to respond to the crises and opportunities of the future. --- “This book is my last battle in my life-long mission to fight devastating ignorance...Previously I armed myself with huge data sets, eye-opening software, an energetic learning style and a Swedish bayonet for sword-swallowing. It wasn’t enough. But I hope this book will be.” Hans Rosling, February 2017.

Although the tenn quality does not have a precise and universally accepted definition, its meaning is generally well understood: quality is what makes the difference between success and failure in a competitive world. Given the importance of quality, there is a need for effective quality systems to ensure that the highest quality is achieved within given constraints on human, material or financial resources. This book discusses Intelligent Quality Systems, that is quality systems employing techniques from the field of Artificial Intelligence (AI). The book focuses on two popular AI techniques, expert or knowledge-based systems and neural networks. Expert systems encapsulate human expertise for solving difficult problems. Neural networks have the ability to learn problem solving from examples. The aim of the book is to illustrate applications of these techniques to the design and operation of effective quality systems. The book comprises 8 chapters. Chapter 1 provides an introduction to quality control and a general discussion of possible AI-based quality systems. Chapter 2 gives technical information on the key AI techniques of expert systems and neural networks. The use of these techniques, singly and in a combined hybrid fonn, to realise intelligent Statistical Process Control (SPC) systems for quality improvement is the subject of Chapters 3-5. Chapter 6 covers experimental design and the Taguchi method which is an effective technique for designing quality into a product or process. The application of expert systems and neural networks to facilitate experimental design is described in this chapter.

R is a language and environment for data analysis and graphics. It may be considered an implementation of S, an award-winning language initially - veloped at Bell Laboratories since the late 1970s. The R project was initiated by Robert Gentleman and Ross Ihaka at the University of Auckland, New Zealand, in the early 1990s, and has been developed by an international team since mid-1997. Historically, econometricians have favored other computing environments, some of which have fallen by the wayside, and also a variety of packages with canned routines. We believe that R has great potential in econometrics, both for research and for teaching. There are at least three reasons for this: (1) R is mostly platform independent and runs on Microsoft Windows, the Mac family of operating systems, and various ?avors of Unix/Linux, and also on some more exotic platforms. (2) R is free software that can be downloaded and installed at no cost from a family of mirror sites around the globe, the Comprehensive R Archive Network (CRAN); hence students can easily install it on their own machines. (3) R is open-source software, so that the full source code is available and can be inspected to understand what it really does, learn from it, and modify and extend it. We also like to think that platform independence and the open-source philosophy make R an ideal environment for reproducible econometric research.
