E-Book Overview
This is a practical introduction to multilevel analysis suitable for all those doing research. Most books on multilevel analysis are written by statisticians; those books are difficult for non-mathematical researchers. In contrast, this volume provides an accessible account on the practical application of multilevel analysis in research. Many worked examples, with computer output, are given to illustrate and explain this subject. Datasets of the examples are available on the internet, so the reader can reanalyze the data. This approach will help bridge the conceptual and communication gap that exists between researchers and statisticians.

Applied Multilevel Analysis A Practical Guide This is a practical introduction to multilevel analysis suitable for all those doing research. Most books on multilevel analysis are written by statisticians, and they focus on the mathematical background. These books are difficult for non-mathematical researchers. In contrast, this volume provides an accessible account on the application of multilevel analysis in research. It addresses the practical issues that confront those undertaking research and wanting to find the correct answers to research questions. This book is written for non-mathematical researchers and it explains when and how to use multilevel analysis. Many worked examples, with computer output, are given to illustrate and explain this subject. Datasets of the examples are available on the Internet, so the reader can reanalyse the data. This approach will help to bridge the conceptual and communication gap that exists between those undertaking research and statisticians. Practical Guides to Biostatistics and Epidemiology Series advisors Susan Ellenberg, University of Pennsylvania School of Medicine Robert C. Elston, Case Western Reserve University School of Medicine Brian Everitt, Institute for Psychiatry, King’s College London Frank Harrell, Vanderbilt University Medical Centre Tennessee Jos W.R. Twisk, Vrije Universiteit Medical Centre, Amsterdam This will be a series of short and practical but authoritative books for biomedical researchers, clinical investigators, public health researchers, epidemiologists, and non-academic and consulting biostatisticians who work with data from biomedical and epidemiological and genetic studies. Some books will be explorations of a modern statistical method and its application, others may focus on a particular disease or condition and the statistical techniques most commonly used in studying it. This series is for people who use statistics to answer specific research questions. Books will explain the application of techniques, specifically the use of computational tools, and emphasize the interpretation of results, not the underlying mathematical and statistical theory.
