Book excerpt: Excerpt from Method of Least Squares Applied to Estimating Errors in Coal Analysis The authors have attacked the problem by first carefully working out the limits for a few coals that are selected as typical and then comparing the results so obtained with data compiled from numerous check determinations taken consecutively from the laboratory records. The number of check determinations was Usually The experimental work was all done by the same analyst; hence the effect of the personal equation was eliminated from the results. On the other hand the data taken from the records include the work of several analysts, so that the personal equation was here involved. Further, the experimental work for a given result took only a day or two, whereas the data represented in the compilation from the records represented at least a month's analyses, so that variations chargeable to changing conditions in the laboratory probably were involved in the recorded results used.

This book was released on 2013-03-14 with total page 777 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Statistics for Economics and Business, Second Edition, provides a comprehensive introduction to the principles of mathematical statistics which underpin statistical analyses in the fields of economics, business, and econometrics. The selection of topics in this textbook is designed to provide students with a conceptual foundation that will facilitate a substantial understanding of statistical applications in these subjects. This new edition has been updated throughout and now also includes a downloadable Student Answer Manual containing detailed solutions to half of the over 300 end-of-chapter problems. After introducing the concepts of probability, random variables, and probability density functions, the author develops the key concepts of mathematical statistics, most notably: expectation, sampling, asymptotics, and the main families of distributions. The latter half of the book is then devoted to the theories of estimation and hypothesis testing with associated examples and problems that indicate their wide applicability in economics and business. Features of the new edition include: a reorganization of topic flow and presentation to facilitate reading and understanding; inclusion of additional topics of relevance to statistics and econometric applications; a more streamlined and simple-to-understand notation for multiple integration and multiple summation over general sets or vector arguments; updated examples; new end-of-chapter problems; a solution manual for students; a comprehensive answer manual for instructors; and a theorem and definition map. This book has evolved from numerous graduate courses in mathematical statistics and econometrics taught by the author, and will be ideal for students beginning graduate study as well as for advanced undergraduates.

Download or read book Statistical Methods in Water Resources written by D.R. Helsel and published by Elsevier. This book was released on 1993-03-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Download or read book Handbook of Coal Analysis written by James G. Speight and published by John Wiley & Sons. This book was released on 2005-05-13 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: All the guidance needed to test coal and analyze the results With the skyrocketing costs of most fuel sources, government, industry, and consumers are taking a greater interest in coal, an abundant and inexpensive alternative, which has been made more environmentally friendly through new technology. Published in response to this renewed interest, Handbook of Coal Analysis provides readers with everything they need to know about testing and analyzing coal. Moreover, it explains the meaning of test results and how these results can predict coal behavior and its corresponding environmental impact during use. The thorough coverage of coal analysis includes: * Detailed presentation of necessary standard tests and procedures * Explanation of coal behavior relative to its usage alongside the corresponding environmental issues * Coverage of nomenclature, terminology, sampling, and accuracy and precision of analysis * Step-by-step test method protocols for proximate analysis, ultimate analysis, mineral matter, physical and electrical properties, thermal properties, mechanical properties, spectroscopic properties, and solvent properties * Emphasis on relevant American Society for Testing and Materials (ASTM) standards and test methods, including corresponding International Organization for Standardization (ISO) and British Standards Institution (BSI) test method numbers To assist readers in understanding the material, a glossary of terms is provided. Each term is defined in straightforward language that enables readers to better grasp complex concepts and theory. References at the end of each chapter lead readers to more in-depth discussions of specialized topics. This is an essential reference for analytical chemists, process chemists, and engineers in the coal industry as well as other professionals and researchers who are looking to coal as a means to decrease dependence on foreign oil sources and devise more efficient, cleaner methods of energy production.
