Book Description
El nivel de esta publicación está adaptado al de los alumnos de los nuevos planes de estudio de las licenciaturas y diplomaturas en Economía y en Administración y Dirección de Empresas de las Facultades y Escuelas Universitarias de Ciencias Económicas y Empresariales: presupone que el lector tiene conocimientos de estadística descriptiva (incluyendo conceptos fundamentales de estadística exploratoria tales como el gráfico tallo y hoja, el gráfico caja y el diagrama esquemático) y de teoría de la probabilidad. El objetivo del libro es doble: en primer lugar, ofrecer una exposición detallada y didáctica de los conceptos estadísticos necesarios para la resolución de problemas prácticos de inferencia estadística en el ámbito económico y empresarial, integrando un enfoque moderno basado en el análisis exploratorio de los datos; en segundo lugar, aportar una guía en la resolución de dichos problemas, dando las soluciones detalladas de cada uno de ellos. Cada capítulo del libro consta de dos partes: en la primera, se presentan los resultados teóricos necesarios para la resolución de los ejercicios; después, se ofrece una colección de ejercicios resueltos.

Book Description
Increased attention is being paid to the need for statistically educated citizens: statistics is now included in the K-12 mathematics curriculum, increasing numbers of students are taking courses in high school, and introductory statistics courses are required in college. However, increasing the amount of instruction is not sufficient to prepare statistically literate citizens. A major change is needed in how statistics is taught. To bring about this change, three dimensions of teacher knowledge need to be addressed: their knowledge of statistical content, their pedagogical knowledge, and their statistical-pedagogical knowledge, i.e., their specific knowledge about how to teach statistics. This book is written for mathematics and statistics educators and researchers. It summarizes the research and highlights the important concepts for teachers to emphasize, and shows the interrelationships among concepts. It makes specific suggestions regarding how to build classroom activities, integrate technological tools, and assess students’ learning. This is a unique book. While providing a wealth of examples through lessons and data sets, it is also the best attempt by members of our profession to integrate suggestions from research findings with statistics concepts and pedagogy. The book’s message about the importance of listening to research is loud and clear, as is its message about alternative ways of teaching statistics. This book will impact instructors, giving them pause to consider: "Is what I’m doing now really the best thing for my students? What could I do better?" J. Michael Shaughnessy, Professor, Dept of Mathematical Sciences, Portland State University, USA This is a much-needed text for linking research and practice in teaching statistics. The authors have provided a comprehensive overview of the current state-of-the-art in statistics education research. The insights they have gleaned from the literature should be tremendously helpful for those involved in teaching and researching introductory courses. Randall E. Groth, Assistant Professor of Mathematics Education, Salisbury University, USA

Book Description
This book addresses two significant research areas in an interdependent fashion. It is first of all a comprehensive but concise text that covers the recently developed and widely applicable methods of qualitative choice analysis, illustrating the general theory through simulation models of automobile demand and use. It is also a detailed study of automobile demand and use, presenting forecasts based on these powerful new techniques. The book develops the general principles that underlie qualitative choice models that are now being applied in numerous fields in addition to transportation, such as housing, labor, energy, communications, and criminology. The general form, derivation, and estimation of qualitative choice models are explained, and the major models - logit, probit, and GEV - are discussed in detail. And continuous/discrete models are introduced. In these, qualitative choice methods and standard regression techniques are combined to analyze situations that neither alone can accurately forecast. Summarizing previous research on auto demand, the book shows how qualitative choice methods can be used by applying them to specific auto-related decisions as the aggregate of individuals' choices. The simulation model that is constructed is a significant improvement over older models, and should prove more useful to agencies and organizations requiring accurate forecasting of auto demand and use for planning and policy development. The book concludes with an actual case study based on a model designed for the investigations of the California Energy Commission. Kenneth Train is Visiting Associate Professor in Economics at the University of California, Berkeley, and Director of Economic Research at Cambridge Systematics, Inc., also in Berkeley. Qualitative Choice Analysisis included in The MIT Press Transportation Studies Series, edited by Marvin L. Manheim.

Book Description
bookdown: Authoring Books and Technical Documents with R Markdown presents a much easier way to write books and technical publications than traditional tools such as LaTeX and Word. The bookdown package inherits the simplicity of syntax and flexibility for data analysis from R Markdown, and extends R Markdown for technical writing, so that you can make better use of document elements such as figures, tables, equations, theorems, citations, and references. Similar to LaTeX, you can number and cross-reference these elements with bookdown. Your document can even include live examples so readers can interact with them while reading the book. The book can be rendered to multiple output formats, including LaTeX/PDF, HTML, EPUB, and Word, thus making it easy to put your documents online. The style and theme of these output formats can be customized. We used books and R primarily for examples in this book, but bookdown is not only for books or R. Most features introduced in this book also apply to other types of publications: journal papers, reports, dissertations, course handouts, study notes, and even novels. You do not have to use R, either. Other choices of computing languages include Python, C, C++, SQL, Bash, Stan, JavaScript, and so on, although R is best supported. You can also leave out computing, for example, to write a fiction. This book itself is an example of publishing with bookdown and R Markdown, and its source is fully available on GitHub.

Book Description
Los métodos estadísticos se aplican al estudio de fenómenos en cuya toma de decisiones prevalecen condiciones de incertidumbre. Esta incertidumbre plantea al investigador la necesidad de medirla, siendo la medida de la incertidumbre la probabilidad.Asociado al concepto de probabilidad está el concepto de variable aleatoria. Una variable aleatoria representa el conjunto de valores que pueden observarse en un fenómeno aleatorio, valores que dependen del azar y sobre los cuales es posible establecer una medida de su probabilidad. Según el número de valores que pueda tomar, la variable aleatoria puede ser discreta o continua.Se denomina distribución de probabilidad de una variable aleatoria a la función que asigna probabilidad a los valores que puede tomar la variable. Cuando se especifican los posibles valores de la variable aleatoria y sus probabilidades respectivas, tenemos construido el modelo de distribución de probabilidad.Este libro se ocupa de ilustrar con ejercicios resueltos todas las facetas del cálculo de probabilidades, incluyendo modelos de distribuciones discretas y continuas.Por otra parte, podemos definir los métodos de inferencia estadística como el conjunto de técnicas que comienzan estudiando la forma de seleccionar una muestra lo suficientemente representativa de una población cuya información permita inferir las propiedades o características de toda la población cometiendo un error medible y acotable. A partir de la muestra, seleccionada mediante un determinado método de muestreo formal, se estiman las características poblacionales (media, total, proporción, etc.) con un error cuantificable y controlable. Las estimaciones se realizan a través de funciones matemáticas de la muestra denominadas estimadores, que se convierten en variables aleatorias al considerar la variabilidad de las muestras. Los errores se cuantifican mediante varianzas, desviaciones típicas o errores cuadráticos medios de los estimadores, que miden la precisión de los mismos.Una parte importante de este libro trata las técnicas de inferencia estadística más habituales incluyendo los modelos de probabildad, estimadores, estimación por intervalos de confianza, contrastes de hipótesis paramétricos y no paramétricos y otras herramientas esenciales en la inferencia estadística.Cada técnica se complementa con una amplia variedad de ejercicios resueltos con STATGRAPHICS que ilustran los conceptos teóricos.

Book Description
Optimal Regulation addresses the central issue of regulatory economics - how toregulate firms in a way that induces them to produce and price "optimally." It synthesizes the majorfindings of an extensive theoretical literature on what constitutes optimality in various situationsand which regulatory mechanisms can be used to achieve it. It is the first text to provide aunified, modern, and nontechnical treatment of the field.The book includes models for regulatingoptimal output, tariffs, and surplus subsidy schemes, and presents all of the material graphically,with clear explanations of often highly technical topics.Kenneth E. Train is Associate AdjunctProfessor in the Department of Economics and Graduate School of Public Policy at the University ofCalifornia, Berkeley. He is also Principal of the firm Cambridge Systematics.Topics include: Thecost structure of natural monopoly (economies of scale and scope). Characterization of firstandsecond-best optimality. Surplus subsidy schemes for attaining first-best optimality. Ramsey pricesand the Vogelsang-Finsinger mechanism for attaining them. Time-ofuse (TOU) prices and Riordan'smechanisms for attaining the optimal TOU prices' Multipart and self-selecting tariffs, and Sibley'smethod for using self-selecting tariffs to achieve optimality. The Averch-Johnson model of howrate-of-return regulation induces inefficiencies. Analysis of regulation based on the firm's returnon Output, costs, or sales. Price-cap regulation. Regulatory treatment of uncertainty and its impacton the firm's behavior. Methods of attaining optimality without direct regulation (contestability,auctioning the monopoly franchise.)
