En este libro se desarrollarán técnicas de aprendizaje supervisado relativas a regresión. Más concretamente, se profundizará en los modelos lineales de regresión múltiple con toda su problemática de identificación, estimación y diagnosis. Se hace especial hincapié en el tratamiento de la multicolinealidad a través de la Ridge Regression (regresión en cadena) y el método PLS de los mínimos cuadrados parciales. Se dedica una parcela importante del contenido a los modelos de variable dependiente limitada y recuento, con especial mención a los modelos Logit y Probit. Por último se tratan también los modelos predictivos del análisis de la varianza y la covarianza.

This book evaluates the contributions of the electronic control unit software of an electric vehicle on sustainability and society, such as the reduction of emissions during a product design and the improvements in the vehicle. A sustainable transport model is proposed, demonstrating its economic viability. By validating software in a more efficient way and adding new functionalities to the software to enhance driving efficiency, energy consumption can be significantly reduced. Therefore, software validation and development have a significant impact on sustainability. This book offers innovative validation solutions based on artificial intelligence techniques to reduce validation time and emissions. The impact of driving efficiency on sustainable transport models is studied in detail, making proposals to be considered in the current environmental policies under discussion within the European Union in order to improve the sustainability of transport models. Vehicles are becoming sophisticated electronic systems due to the fact that they are integrating a significant number of electronic control units. This trend will certainly continue in the year to come. Consequently, software validation techniques are a key element for car manufacturers in order to ensure the quality of the vehicle. This book contributes to these efforts.

La investigación constituye una tarea necesaria en la intervención y práctica en el ámbito de la educación, fundamentalmente se orienta a la búsqueda de alternativas, la comprensión de hechos y situaciones desde su complejidad, la consecución de soluciones, la transformación y el cambio. Por ello, investigar no puede concebirse como una tarea ajena que asuman solo los especialistas; investigar la realidad socioeducativa o pedagógica es la vía de innovación y mejora de la práctica profesional; pero en los procesos de investigación la estadística da rigor científico a las conclusiones obtenidas con datos recopilados. Los medios tecnológicos vigentes permiten un trabajo liviano para el investigador, pero a su vez riguroso y profundo. En este contexto el programa estadístico-informático R toma un papel destacado por su facilidad y libertad de uso, sin ninguna atadura a empresas comercializadoras de software y con una presencia relevante en las universidades y centros de investigación de todo el mundo. El texto que se presenta aborda, con la ayuda del programa R, en cinco temas, las tareas fundamentales que afronta cualquier investigador en el ámbito de las ciencias sociales. En primer lugar, se fijan los rudimentos del programa R en el entorno de trabajo RCommander; después se habla de la organización y manipulación de los datos; más tarde de la representación de la información. Con estos tres temas se cubren los aspectos descriptivos básicos del análisis de datos. En el tema cuatro se trata las relaciones entre variables. Finalmente, el quinto tema se adentra en el tratamiento de datos textuales. La visión del texto es eminentemente práctica, con algunas formulaciones matemáticas de ayuda. Además, todos los capítulos están ilustrados con ejemplos relacionados con las ciencias sociales.
