El libro recorre el tema del análisis estadístico de datos categóricos, necesario para que los profesionales de las áreas biológicas, agrícolas, de salud y afines adquieran los conocimientos y herramientas necesarios para un apropiado análisis de datos. En los primeros capítulos se exponen y afianzan conceptos básicos orientados a la comprensión de las herramientas de análisis de datos expuestas en los capítulos posteriores. Se introducen conceptos de estadística no paramétrica como alternativa de análisis, ya que, en la mayoría de los casos, los datos categóricos provenientes de los estudios biológicos no satisfacen los supuestos estadísticos estándar. Se hace especial énfasis en la implementación de los análisis haciendo uso del software libre R.

A visually intuitive approach to statistical data analysis Visual Statistics brings the most complex and advanced statistical methods within reach of those with little statistical training by using animated graphics of the data. Using ViSta: The Visual Statistics System-developed by Forrest Young and Pedro Valero-Mora and available free of charge on the Internet-students can easily create fully interactive visualizations from relevant mathematical statistics, promoting perceptual and cognitive understanding of the data's story. An emphasis is placed on a paradigm for understanding data that is visual, intuitive, geometric, and active, rather than one that relies on convoluted logic, heavy mathematics, systems of algebraic equations, or passive acceptance of results. A companion Web site complements the book by further demonstrating the concept of creating interactive and dynamic graphics. The book provides users with the opportunity to view the graphics in a dynamic way by illustrating how to analyze statistical data and explore the concepts of visual statistics. Visual Statistics addresses and features the following topics: * Why use dynamic graphics? * A history of statistical graphics * Visual statistics and the graphical user interface * Visual statistics and the scientific method * Character-based statistical interface objects * Graphics-based statistical interfaces * Visualization for exploring univariate data This is an excellent textbook for undergraduate courses in data analysis and regression, for students majoring or minoring in statistics, mathematics, science, engineering, and computer science, as well as for graduate-level courses in mathematics. The book is also ideal as a reference/self-study guide for engineers, scientists, and mathematicians. With contributions by highly regarded professionals in the field, Visual Statistics not only improves a student's understanding of statistics, but also builds confidence to overcome problems that may have previously been intimidating.

Corporate Spin-Off processes are very interesting phenomena formanagement theory and practice. In theory, Corporate Spin-Offs areboth a driver and a result of organisational change, offering thepossibility to investigate an area where companies are genuinelysharing experience and best practice. Although Corporate Spin-Offs canbe clearly distinguished from other types of start-ups and divestmentsand despite combining key-characteristics in a unique way, existinginvestigation is sparse and heterogeneous. In practice, CorporateSpin-Off processes are frequent and highly successful, but not aswell-regarded as Merger & Acquisition strategies and less understoodby the decision-makers.The present work was designed to meet these demands by analysing thesuccess factors of Corporate Spin-Offs, their relative contribution tothe process and the role of the different actors involved. Based on anextensive literature review and a new Spin-Off typology, a broad rangeof success factors and success dimensions is proposed. Using acombination of multivariate models, the responses from 211 Europeancompanies to a questionnaire are analysed and typologies derived.Among the single factors, customer participation, the transfer ofmanagerial and market-related experience and the main motivation arethe most important ones for the Spin-Off process and its success. Thetypologies reveal characteristic factors sets, showing for examplethat high-growth Spin-Offs benefited over-proportionally from sectorgrowth or the access to relations with customers or suppliers. Thisproduces a new and comprehensive perspective on the relativecontribution of each success factor, their interaction, and thebehaviour of both the parentand the Spin-Off companies in theprocess. These results are highly valuable for managers, scientists inthe field and policy-makers.

Assessment in natural contexts through observation is unquestionably complex. Systematic observation grounded in observational methodology offers a wide range of possibilities to the rigorous study of everyday behavior in their natural context. These possibilities have been enriched in recent decades with the explosion of information and communication technologies. In this eBook we assemble 23 articles from several researchers who have made important contributions to this evolving field. The articles included in this eBook has been organized with a first part on general methodological developments and a second part with methodological contributions that emphasize different application areas. Considering the enormous possibilities of the systematic observation in the study of daily life, we hope this eBook will be useful to understand innovative applications in different fields.

The book is a collective work by a number of leading scientists, analysts, engineers, mathematicians and statisticians who have been working at the forefront of data analysis and related applications, arising from data science, operations research, engineering, machine learning or statistics. The chapters of this collaborative work represent a cross-section of current research interests in the above scientific areas. The collected material has been divided into appropriate sections to provide the reader with both theoretical and applied information on data analysis methods, models and techniques, along with appropriate applications. The published data analysis methodology includes the updated state-of-the-art rapidly developed theory and applications of data expansion, both of which go through outstanding changes nowadays. New approaches are expected to deliver and have been developed, including Artificial Intelligence.

El libro recoge 38 aportaciones sobresalientes al IV Congreso Europeo de Psicología Comunitaria representativas del trabajo teórico, práctico e investigador realizado por psicólogos comunitarios en Europa y Latinoamérica, agrupadas, según el tema, en 4 capítulos. El capítulo 1 presenta los valores sociales de varias poblaciones así como algunas dinámicas educativas y transculturales de esos valores en nuestros días. En el capítulo 2 se hacen reflexiones y propuestas éticas sobre el trabajo comunitario en tiempos de conformismo. Los artículos del capítulo 3 analizan comunidad -y su vivencia psicológica- como temas centrales de la Psicología Comunitaria y del debate social moderno y postmoderno. El capítulo 4 agrupa experiencias e intervenciones comunitarias en los ámbitos de emigración, salud, política y educación. En dos capítulos adicionales, los compiladores, introducen y sacan conclusiones teóricas y prácticas de lo expuesto el libro, identificando la comunidad, el poder, la ética y los valores como temas nucleares. El volumen es de interés para estudiantes, académicos y practicantes de “lo social” desde distintas perspectivas y profesiones...The book gathers 38 contributions to the IV European Congress on Community Psychogy representative of the theoretical, practical, and research work done by community psychologists around Europe and Latin America.
