Introduction to Robust Estimation and Hypothesis Testing

Autor: Rand R. Wilcox

Número de Páginas: 812

Introduction to Robust Estimating and Hypothesis Testing, 4th Editon, is a 'how-to' on the application of robust methods using available software. Modern robust methods provide improved techniques for dealing with outliers, skewed distribution curvature and heteroscedasticity that can provide substantial gains in power as well as a deeper, more accurate and more nuanced understanding of data. Since the last edition, there have been numerous advances and improvements. They include new techniques for comparing groups and measuring effect size as well as new methods for comparing quantiles. Many new regression methods have been added that include both parametric and nonparametric techniques. The methods related to ANCOVA have been expanded considerably. New perspectives related to discrete distributions with a relatively small sample space are described as well as new results relevant to the shift function. The practical importance of these methods is illustrated using data from real world studies. The R package written for this book now contains over 1200 functions. New to this edition - 35% revised content - Covers many new and improved R functions - New techniques that deal with a ...

Robust Statistics

Autor: Ricardo A. Maronna , R. Douglas Martin , Victor J. Yohai , Matías Salibián-barrera

Número de Páginas: 466

A new edition of this popular text on robust statistics, thoroughly updated to include new and improved methods and focus on implementation of methodology using the increasingly popular open-source software R. Classical statistics fail to cope well with outliers associated with deviations from standard distributions. Robust statistical methods take into account these deviations when estimating the parameters of parametric models, thus increasing the reliability of fitted models and associated inference. This new, second edition of Robust Statistics: Theory and Methods (with R) presents a broad coverage of the theory of robust statistics that is integrated with computing methods and applications. Updated to include important new research results of the last decade and focus on the use of the popular software package R, it features in-depth coverage of the key methodology, including regression, multivariate analysis, and time series modeling. The book is illustrated throughout by a range of examples and applications that are supported by a companion website featuring data sets and R code that allow the reader to reproduce the examples given in the book. Unlike other books on the...

World Atlas of Jellyfish

Autor: Gerhard Jarms , André Morandini

Número de Páginas: 828

The »World Atlas of Jellyfish« presents in a lavishly illustrated multi-author compendium the more than 260 species of medusae (Scyphomedusae and Cubomedusae) described so far. The general, first part deals with their structure, complex life cycles and rare fossil records. But it also details on collection, cultivation and fishery methods, even gives hints for photography and cooking recipes. Additionally, it covers the nature of medusae venoms, the effects and treatment of their stings. The second part gives concise systematic descriptions of all jellyfish species and their developmental stages known so far. Numerous illustrations, distribution maps, taxonomic keys and literature lists allow for detailed identification and information. Outstanding among the wealth of wonderful illustrations are hitherto unpublished artistic colour paintings by Ernst Haeckel. The beauty of the animals is underlined by the demanding typesetting of the book. This »Atlas« is a unique overview summarizing our knowledge on the world's jellyfish in all their facets. It is of importance not only for scientists worldwide, but also a source of fascination for divers and lovers of marine life....

Esta novela fue escrita en una época lejana en la que veíamos películas en videocasetes, escuchábamos música en walkman, mandábamos mensajes por fax, las cámaras de fotos llevaban rollos, todavía volaba el Concorde y Luis vivía en México. A pesar de la distancia con la Argentina y por ganas de jugar juntos, se nos ocurrió escribir a cuatro manos. Teníamos un comienzo que combinaba los primeros párrafos de El Quijote, Cien años de soledad y La metamorfosis, y se lo atribuimos a un personaje que plagiaba torpemente para seducir a una mujer cuya debilidad eran los escritores. Creo recordar que empezamos en Buenos Aires, con un esquema de los personajes y un posible recorrido, y luego continuamos vía e-mail, con algún encuentro en México y más tarde en España, entre 1997 y 2000. Escribíamos por turnos, y cada uno podía decidir hacia dónde continuaba la narración, pero sabíamos que queríamos llegar a que este escritor triunfara a pesar de lo evidente de su plagio. Jorge.Iba a escribir lo mismo. Mejor cuento que un día nos encontramos a comer y Jorge llegó con el párrafo inicial. Yo esperaba la comida, obviamente; pero era lo que había. El resto lo...
