    Bayesian Nonparametric Data Analysis
    (2015) Müller, Peter; Quintana Quintana, Fernando Andrés; Jara, Alejandro; Hanson, Tim
    This book reviews nonparametric Bayesian methods and models that have proven useful in the context of data analysis. Rather than providing an encyclopedic review of probability models, the book’s structure follows a data analysis perspective. As such, the chapters are organized by traditional data analysis problems. In selecting specific nonparametric models, simpler and more traditional models are favored over specialized ones.The discussed methods are illustrated with a wealth of examples, including applications ranging from stylized examples to case studies from recent literature. The book also includes an extensive discussion of computational methods and details on their implementation. R code for many examples is included in online software pages

    Determinación de la alimentación de pollos broiler
    (2020) Santana Romo, Fabián Mauricio
    En la presente investigación se usaron fuentes alternas de proteína dentro de la alimentación balanceada de los pollos de engorde (Gallus gallus). Se consideraron granos de la región tales como la soya (Glycine max) y el chocho (Lupinus mutabilis) por su gran contenido proteico y por la facilidad de obtenerlos y procesarlos. Estos se sustituyeron en porcentajes de 0 (Testigo Experimental), 25, 50 y 75% del balanceado comercial. La etapa de levante, que comprende desde el día 1 hasta el día 28, dejó como conclusión que porcentajes de 50% balanceado comercial y 50% de soya son los mejores para tener un aumento de peso superior al reportado en tablas por casas comerciales. Los tratamientos propuestos producen el mismo aumento de peso en las aves; se redujo la cantidad de balanceado comercial y se aumentó la fuente de proteína alterna resultando en menores costos de producción y carne más sana y apetecible.

    Generalized Kernel Equating with Applications in R
    (Taylor & Francis, 2024) Wiberg, Marie; González Burgos, Jorge Andrés; von Davier, Alina A.
    Generalized Kernel Equating is a comprehensive guide for statisticians, psychometricians, and educational researchers aiming to master test score equating. This book introduces the Generalized Kernel Equating (GKE) framework, providing the necessary tools and methodologies for accurate and fair score comparisons.The book presents test score equating as a statistical problem and covers all commonly used data collection designs. It details the five steps of the GKE framework: presmoothing, estimating score probabilities, continuization, equating transformation, and evaluating the equating transformation. Various presmoothing strategies are explored, including log-linear models, item response theory models, beta4 models, and discrete kernel estimators. The estimation of score probabilities when using IRT models is described and Gaussian kernel continuization is extended to other kernels such as uniform, logistic, epanechnikov and adaptive kernels. Several bandwidth selection methods are described. The kernel equating transformation and variants of it are defined, and both equating-specific and statistical measures for evaluating equating transformations are included. Real data examples, guiding readers through the GKE steps with detailed R code and explanations are provided. Readers are equipped with an advanced knowledge and practical skills for implementing test score equating methods.

    Quantum Optics - An Introduction
    (Wiley-Vch, 2001) Wallentowitz, Sascha; Vogel, Werner; Welsch, Dirk-Gunnar
    This is the revised and supplemented edition of the acknowledged "Lectures on Quantum Optics" by W. Vogel and D.-G. Welsch. It offers theoretical concepts of quantum optics, with special emphasis on current research trends. Quantum-state reconstruction and laser-driven quantized motion of trapped atoms are new topics that are included in the revised edition. The rigorous development of quantum optics in the context of quantum field theory and the attention spent to details make the book valuable to graduate students as well as to researchers in related areas.
