This book was released on 2003-04-11 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cuando se dispone de información suplementaria puede ser ventajoso, de cara a obtener estimaciones más precisas, poder incorporarla. En el primer capítulo se revisan los distintos métodos de estimación que hacen uso de la información auxiliar disponible, por medio del muestreo doble, a cuya técnica se dedica el segundo capítulo, con el objetivo de estimar la media o el total de una población finita. En algunos casos se dispone de información adicional referida a más de una ariable auxiliar, y en tales circunstancias lo más adecuado será utilizar toda la información existente para mejorar la precisión de las estimaciones. Así, en el tercer capítulo se proponen estimadores indirectos multivariantes de doble muestreo (razón, producto, diferencia, razón-producto) bajo un diseño de muestreo en ocasiones sucesivas. En el cuarto capítulo se propone la estimación de otros parámetros, tales como la razón y el producto de medias poblacionales, considerando que las muestras son seleccionadas bajo un diseño de muestreo en dos ocasiones. Finalmente, el quinto capítulo se dedica a extender la teoría sobre muestreo sucesivo a otros diseños muestrales más complejos como el muestreo con probabilidades proporcionales al tamaño y el muestreo estratificado. Se dan las condiciones que demuestran la mejora en eficiencia de los métodos propuestos, junto con la expresión del estimador óptimo, su varianza y la fracción óptima que debe solaparse. Se presentan resultados para algunos casos especiales de aplicación práctica.

This book was released on 2009-05-26 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Las técnicas indirectas de estimación en muestreo de poblaciones finitas tratan de mejorar, en la fase de estimación, mediante el conocimiento de información suplementaria aportada por una o varias variables auxiliares, la precisión de los estimadores directos que no utilizan más que la información que proporciona la observación de la variable de interés en la muestra seleccionada. En esta tesis se presenta una visión conjunta de las técnicas indirectas de estimación y el método del muestreo en ocasiones sucesivas, diseño muestral que es utilizado en gran cantidad de encuestas continuas elaboradas por el Instituto Nacional de Estadística, como es el caso de la Encuesta de Población Activa. Bajo un diseño de muestreo en dos ocasiones se aborda el problema de la estimación de parámetros poblacionales, tales como la media, la varianza, la mediana, la razón y el producto de medias. Para los estimadores propuestos se obtiene la fracción óptima de la muestra que debe solaparse, así como las condiciones bajo las cuales, dichos estimadores mejoran en precisión al correspondiente estimador directo y a estimadores indirectos propuestos por otros autores.

Available in PDF, EPUB and Kindle. Book excerpt: El propósito de este libro es presentar de una manera amigable y sencilla los diferentes conceptos involucrados en la teoría del muestreo probabilístico desde una óptica clásica. Siendo el muestreo una de las formas básicas de la estadística para obtener información con el fin de satisfacer necesidades establecidas en proyectos de investigación de diferente índole y cobertura, se constituye en el mundo de hoy con más fuerza en una metodología científica para la toma de decisiones mediante el uso de la inferencia estadística. Basta con considerar el tamaño de los colectivos objeto de estudio, la dificultad en tiempo y dinero para llegar a todos los elementos que los componen y, en algunos casos, los riesgos por destrucción que se tendrían para poder observarlos (medirlos), así como la dificultad de su acceso, situaciones que obligan en cualquier campo del conocimiento a la toma de una muestra probabilística de dicho colectivo. Tres aspectos son de suma importancia en la obtención de una muestra probabilística desde el punto de vista práctico: en primer lugar, la forma como serán obtenidas las unidades que conformarán la muestra, la cual debe estar regida por la aleatoriedad para evitar sesgos de selección; en segundo lugar, el tamaño de dicha muestra soportada sobre la base de supuestos teóricos para la distribución (comportamiento) del estimador asociado al parámetro investigado, el error asumido con la estimación debido a la diferencia entre la estimación y el parámetro objeto de estimación, y el nivel de confianza en términos de probabilidad que se desea tenga el cumplimiento de dicho error; y, en tercer lugar, los costos involucrados en la obtención de dicha muestra, pues nadie niega la importancia de trabajar con muestras económicas

Download or read book Qualitative Choice Analysis written by Kenneth Train and published by MIT Press. This book was released on 1986 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

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.)
