Dentro de las técnicas de segmentación de mercados se distingue entre técnicas predictivas, en las que las variables que intervienen en el proceso pueden clasificarse inicialmente en dependientes e independientes (similares a las técnicas del análisis de la dependencia o métodos explicativos del análisis multivariante) y técnicas descriptivas, en las que todas las variables tienen inicialmente el mismo estatus (similares a las técnicas del análisis de la interdependencia o métodos descriptivos del análisis multivariante). Las técnicas predictivas de segmentación especifican el modelo para los datos en base a un conocimiento teórico previo. El modelo supuesto para los datos debe contrastarse después del proceso de minería de datos antes de aceptarlo como válido. En algunos casos, el modelo se obtiene como mezcla del conocimiento obtenido antes y después de la segmentación y también debe contrastarse antes de aceptarse como válido. Por ejemplo, las redes neuronales permiten descubrir modelos complejos y afinarlos a medida que progresa la exploración de los datos. Gracias a su capacidad de aprendizaje, permiten descubrir relaciones complejas entre variables sin ninguna intervención externa. Podemos incluir entre estas técnicas todas las técnicas de segmentación en las que subyace un modelo (modelos de elección discreta, análisis discriminante, árboles de decisión, redes neuronales, análisis conjunto, etc.) Estas técnicas también se denominan técnicas de clasificación ya que permiten extraer perfiles de comportamiento o clases, siendo el objetivo construir un modelo que permita clasificar cualquier nuevo dato en una de las clases.En las técnicas descriptivas no se asigna ningún papel predeterminado a las variables. No se supone la existencia de variables dependientes ni independientes y tampoco se supone la existencia de un modelo previo para los datos. Los modelos se crean automáticamente partiendo del reconocimiento de patrones. En este grupo se incluyen las técnicas de clustering y las técnicas de reducción de la dimensión (escalamiento multidimensonal, correspondencias, etc.) En este libro se tratan las técnicas predictivas y descriptivas que suelen implementarse en herramientas de Minería de Datos, presentndo ejemplos prácticos totalmente resueltos.

Este libro presenta, desde un punto de vista eminentemente práctico, el lugar que ocupa el análisis de la información en la investigación comercial, y los métodos de análisis mas comúnmente empleados para fundamentar las decisiones de marketing más habituales. Dado que la mayoría de los problemas de márketing son "multidimensionales", esta obra se dedica principalmente a los métodos de "análisis multivariable": cuándo debe usarse cada método, cuál es su metodología básica, cuáles son sus aplicaciones al marketing y cómo pueden y deben interpretarse los resultados que de ellos se obtengan. También se hace referencia a los métodos de análisis "uni" y "bivariable", ya que unos y otros son un complemento de análisis fundamental tanto para obtener una "primera impresión" sobre el problema que se investiga como para poder "caracterizar" a los segmentos de interés, una vez determinados.

This book reports new results in condensed matter physics for which topological methods and ideas are important. It considers, on the one hand, recently discovered systems such as carbon nanocrystals and, on the other hand, new topological methods used to describe more traditional systems such as the Fermi surfaces of normal metals, liquid crystals and quasicrystals. The authors of the book are renowned specialists in their fields and present the results of ongoing research, some of it obtained only very recently and not yet published in monograph form.

Winner of the 2003 Senior Book Prize from the American Ethnological Society. Cholas and Pishtacos are two provocative characters from South American popular culture—a sensual mixed-race woman and a horrifying white killerwho show up in everything from horror stories and dirty jokes to romantic novels and travel posters. In this elegantly written book, these two figures become vehicles for an exploration of race, sex, and violence that pulls the reader into the vivid landscapes and lively cities of the Andes. Weismantel's theory of race and sex begins not with individual identity but with three forms of social and economic interaction: estrangement, exchange, and accumulation. She maps the barriers that separate white and Indian, male and female-barriers that exist not in order to prevent exchange, but rather to exacerbate its inequality. Weismantel weaves together sources ranging from her own fieldwork and the words of potato sellers, hotel maids, and tourists to classic works by photographer Martin Chambi and novelist José María Arguedas. Cholas and Pishtacos is also an enjoyable and informative introduction to a relatively unknown region of the Americas.

Hundreds of grassroots groups have sprung up around the world to teach programming, web design, robotics, and other skills outside traditional classrooms. These groups exist so that people don't have to learn these things on their own, but ironically, their founders and instructors are often teaching themselves how to teach. There's a better way. This book presents evidence-based practices that will help you create and deliver lessons that work and build a teaching community around them. Topics include the differences between different kinds of learners, diagnosing and correcting misunderstandings, teaching as a performance art, what motivates and demotivates adult learners, how to be a good ally, fostering a healthy community, getting the word out, and building alliances with like-minded groups. The book includes over a hundred exercises that can be done individually or in groups, over 350 references, and a glossary to help you navigate educational jargon.

This volume presents both an analysis of how identities are built, represented and negotiated in narrative, as well as a theoretical reflection on the links between narrative discourse and identity construction. The data for the book are Mexican immigrants' personal experience narratives and chronicles of their border crossings into the United States. Embracing a view of identity as a construct firmly grounded in discourse and interaction, the author examines and illustrates the multiple threads that connect the local expression and negotiation of identity to the wider social contexts that frame the experience of migration, from material conditions of life in the United States to mainstream discourses about race and color. The analysis reveals how identities emerge in discourse through the interplay of different levels of expression, from implicit adherence to narrative styles and ways of telling, to explicit negotiation of membership categories.
