Download or read book Sample Size Determination in Health Studies written by S. Kaggwa Lwanga and published by . This book was released on 1991 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual presents the practical and statistical information needed to help investigators decide how large a sample to select from a population targeted for a health study or survey. Designed to perform a "cookbook" function, the book uses explanatory text and abundant tabular calculations to vastly simplify the task of determining the minimum sample size needed to obtain statistically valid results. The objective is to assist those investigators, undertaking health studies at local or district level, who lack detailed knowledge of statistical methodology.

This book was released on 2023-04-02 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an open access book. The National Research and Innovation Agency (Acronymized in Bahasa as BRIN, Badan Riset and Inovasi Nasional), the Republic of Indonesia was launched in 2021 and has been the only one of Indonesia authorized research institution since. The Agency embodies throughout department and non-department research bodies in Indonesia and answers and thus responsible directly to the President of Indonesia. Despite its juvenile age, BRIN is in a tight competition with urgencies of untangling unresolved issues in various aspects in collective life as a nation and a state spanning socioeconomic and culture to medicine and its translational derivatives. To function as effectively as expected, BRIN has launched 12 research organizations with each is accountable for a specific research field as reflected by the expertise of the pertinent researchers. Among those, Research Organization for Health was established as an answer to the major challenge of overcoming national burdens which are holistically captured as the roadmaps of SDG’s Indonesia where Health stands specially as the top three priority and regarded as Good Health-Wellbeing. It is clear that what have been produced through long chain of processes in the research chambers must be driven forward and translated accordingly to reach downstream utilizations in such a way that the good health and well-being are reachable in any levels. As to manifesting these goals into realization, knowledge sharing is deemed to be a plausible vehicle. This enables disseminations of most current research projects related to health across research institution, regionally or globally. Therefore, we see the need to organize our very first international conference that is, further, set as one of our annual events with contemporary umbrella themes. We welcome researchers, scholars, and practitioners in health and health-related fields to share their insightful research results in our conference. The general objective of BRIN’s 1st International Conference for Health (ICHR) is to facilitate dissemination and exchange of most recent progresses made across research institutions and to promote prospectus multi-nationals and or multi-institutional collaborations to achieve the good-health and well-being.

Download or read book Statistical Methods in Medical Research written by Peter Armitage and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explanation and implementation of statistical methods for the medical researcher or statistician remains an integral part of modern medical research. This book explains the use of experimental and analytical biostatistics systems. Its accessible style allows it to be used by the non-mathematician as a fundamental component of successful research. Since the third edition, there have been many developments in statistical techniques. The fourth edition provides the medical statistician with an accessible guide to these techniques and to reflect the extent of their usage in medical research. The new edition takes a much more comprehensive approach to its subject. There has been a radical reorganization of the text to improve the continuity and cohesion of the presentation and to extend the scope by covering many new ideas now being introduced into the analysis of medical research data. The authors have tried to maintain the modest level of mathematical exposition that characterized the earlier editions, essentially confining the mathematics to the statement of algebraic formulae rather than pursuing mathematical proofs.

Download or read book Epidemiological Research Methods written by Donald R. McNeil and published by John Wiley & Sons. This book was released on 1996-08-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concepts of epidemiology, the science that uses statistical methods to investigate associations between risk factors and disease outcomes in human populations, are developed using examples involving real data from published studies. The relevant statistical methods are developed systematically to provide an integrated approach to observational and experimental studies. After covering basic measurement, study design, and study credibility issues, the author continues with basic statistical methods and techniques for adjusting risk estimates for confounders. Statistical models including logistic regression and the proportional hazards model for survival analysis are explained in detail in the following chapters, concluding with an explanation of the general methods for determining the sample size and power requirements for an epidemiological study. Taking advantage of the power, accessibility and user-friendliness of modern computer packages, the author uses a variety of interesting data sets and graphical displays to illustrate the methods. Epidemiological Research Methods will be of interest to students and research workers who need to learn and appreciate modern approaches to the subject. Without unnecessary emphasis on mathematics or theory, the book will enable the reader to gain a greater level of understanding of the underlying methods than is normally provided in books on epidemiology.

Available in PDF, EPUB and Kindle. Book excerpt: A trusted classic on the key methods in population sampling—now in a modernized and expanded new edition Sampling of Populations, Fourth Edition continues to serve as an all-inclusive resource on the basic and most current practices in population sampling. Maintaining the clear and accessible style of the previous edition, this book outlines the essential statistical methodsfor survey design and analysis, while also exploring techniques that have developed over the past decade. The Fourth Edition successfully guides the reader through the basic concepts and procedures that accompany real-world sample surveys, such as sampling designs, problems of missing data, statistical analysis of multistage sampling data, and nonresponse and poststratification adjustment procedures. Rather than employ a heavily mathematical approach, the authors present illustrative examples that demonstrate the rationale behind common steps in the sampling process, from creating effective surveys to analyzing collected data. Along with established methods, modern topics are treated through the book's new features, which include: A new chapter on telephone sampling, with coverage of declining response rates, the creation of "do not call" lists, and the growing use of cellular phones A new chapter on sample weighting that focuses on adjustments to weight for nonresponse, frame deficiencies, and the effects of estimator instability An updated discussion of sample survey data analysis that includes analytic procedures for estimation and hypothesis testing A new section on Chromy's widely used method of taking probability proportional to size samples with minimum replacement of primary sampling units An expanded index with references on the latest research in the field All of the book's examples and exercises can be easily worked out using various software packages including SAS, STATA, and SUDAAN, and an extensive FTP site contains additional data sets. With its comprehensive presentation and wealth of relevant examples, Sampling of Populations, Fourth Edition is an ideal book for courses on survey sampling at the upper-undergraduate and graduate levels. It is also a valuable reference for practicing statisticians who would like to refresh their knowledge of sampling techniques.
