Treats linear regression diagnostics as a tool for application of linear regression models to real-life data. Presentation makes extensive use of examples to illustrate theory. Assesses the effect of measurement errors on the estimated coefficients, which is not accounted for in a standard least squares estimate but is important where regression coefficients are used to apportion effects due to different variables. Also assesses qualitatively and numerically the robustness of the regression fit.
Major text including chapters on the following: defining outcome measures; assessing heterogeneity; using fixed effects methods and random effects models for combining study estimates; publication bias.
Research in Medical and Biological Sciences covers the wide range of topics that a researcher must be familiar with in order to become a successful biomedical scientist. Perfect for aspiring as well as practicing professionals in the medical and biological sciences, this publication discusses a broad range of topics that are common yet not traditionally considered part of formal curricula, including philosophy of science, ethics, statistics, and grant applications. The information presented in this book also facilitates communication across conventional disciplinary boundaries, in line with the increasingly multidisciplinary nature of modern research projects. - Covers the breadth of topics that a researcher must understand in order to be a successful experimental scientist - Provides a broad scientific perspective that is perfect for students with various professional backgrounds - Contains easily accessible, concise material about diverse methods - Includes extensive online resources such as further reading suggestions, data files, statistical tables, and the StaTable application package - Emphasizes the ethics and statistics of medical and biological sciences
It is 46 years since the 1st publication of Sir Stanley Davidson's textbook, Principles and Practice of Medicine. Since that time, the book has gone through many changes, establishing an international reputation for innovation and clarity.

This program, companion software to the text "Statistical Power Analysis, Second Edition, " includes the following features: * Spreadsheet Input. Data may be entered by means of a spreadsheet interface. As any cells in the spreadsheet (Mean, SD, N, Alpha, Tails, etc.) are modified by the user, the value of Effect Size and Power are simultaneously updated. * Graphic Input. Alternatively, data may be entered by means of a graphic interface. Cursor keys are used to modify graphs of the group distributions, and the value of power is updated in response. * Active HELP Screens. In addition to providing instructions and explanations, the HELP screens function as worksheets which enable the user to ...
