The Missing Pairs

Illustrations and easy-to-read text follow Bear as he tries to help Fox, Hare, and Badger find one missing sock, one missing mitten, and one missing boot--but no missing pears.

JavaScript lets you supercharge your HTML with animation, interactivity, and visual effects—but many web designers find the language hard to learn. This easy-to-read guide not only covers JavaScript basics, but also shows you how to save time and effort with the jQuery and jQuery UI libraries of prewritten JavaScript code. You’ll build web pages that feel and act like desktop programs—with little or no programming. The important stuff you need to know: Pull back the curtain on JavaScript. Learn how to build a basic program with this language. Get up to speed on jQuery. Quickly assemble JavaScript programs that work well on multiple web browsers. Transform your user interface. Learn jQuery UI, the JavaScript library for interface features like design themes and controls. Make your pages interactive. Create JavaScript events that react to visitor actions. Use animations and effects. Build drop-down navigation menus, pop-ups, automated slideshows, and more. Collect data with web forms. Create easy-to-use forms that ensure more accurate visitor responses. Practice with living examples. Get step-by-step tutorials for web projects you can build yourself.

Missing data pose challenges to real-life data analysis. Simple ad-hoc fixes, like deletion or mean imputation, only work under highly restrictive conditions, which are often not met in practice. Multiple imputation replaces each missing value by multiple plausible values. The variability between these replacements reflects our ignorance of the true (but missing) value. Each of the completed data set is then analyzed by standard methods, and the results are pooled to obtain unbiased estimates with correct confidence intervals. Multiple imputation is a general approach that also inspires novel solutions to old problems by reformulating the task at hand as a missing-data problem. This is the second edition of a popular book on multiple imputation, focused on explaining the application of methods through detailed worked examples using the MICE package as developed by the author. This new edition incorporates the recent developments in this fast-moving field. This class-tested book avoids mathematical and technical details as much as possible: formulas are accompanied by verbal statements that explain the formula in accessible terms. The book sharpens the reader’s intuition on how to think about missing data, and provides all the tools needed to execute a well-grounded quantitative analysis in the presence of missing data.

This work is the first to focus systematically on a much-debated topic: the conceptual issues of community ecology, including the nature of evidence in ecology, the role of experiments, attempts to disprove hypotheses, and the value of negative evidence in the discipline. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

In the Dictionary of Plant Genetics and Molecular Biology, more than 3,500 technical terms from the fields of plant genetics and molecular biology are defined for students, teachers, and researchers in universities, institutes, and agricultural research stations. An excellent educational tool that will save you time and effort, this dictionary brings together into a single source the meaning and origin of terms from the fields of classical genetics, molecular genetics, mutagenesis, population genetics, statistics, plant biotechnology, evolutionary genetics, plant breeding, and plant biotechnology. Finding and understanding the precise meaning of many terms in genetics is crucial to understanding the foundation of the subject matter. For reasons of space, the glossaries provided at the end of most textbooks are highly inadequate. There is, then, dire need for a dictionary of terms in a single volume. You?ll appreciate the helpful approaches and features of Dictionary of Plant Genetics and Molecular Biology, including: no terms that are of limited use, very general, or self-explanatory cross references for effective access to the materials and economy of space alternate names of terms, denoted with “Also referred to as . . .” or “Also known as . . .” multiple definitions for terms defined by different authors or for terms with different meanings in different contexts authors who coined, described, or contributed toward further understanding of a term are listed and respective publications are included in the Bibliography At last, there is compiled in a single volume the technical terms you need to know in order to understand plant genetics and molecular biology. As your knowledge grows, you?ll uncover even more terms that you need to understand. You?ll find yourself turning to this handy guide time and time again for help on all levels.

The work presented in this thesis spans a wide range of experimental particle physics subjects, starting from level-1 trigger electronics to the final results of the search for Higgs boson decay and to tau lepton pairs. The thesis describes an innovative reconstruction algorithm for tau decays and details how it was instrumental in providing a measurement of Z decay to tau lepton pairs. The reliability of the analysis is fully established by this measurement before the Higgs boson decay to tau lepton pairs is considered. The work described here continues to serve as a model for analysing CMS Higgs to tau leptons measurements.
