Download or read book Small Sample Size Solutions written by Rens van de Schoot and published by Routledge. This book was released on 2020-02-13 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers often have difficulties collecting enough data to test their hypotheses, either because target groups are small or hard to access, or because data collection entails prohibitive costs. Such obstacles may result in data sets that are too small for the complexity of the statistical model needed to answer the research question. This unique book provides guidelines and tools for implementing solutions to issues that arise in small sample research. Each chapter illustrates statistical methods that allow researchers to apply the optimal statistical model for their research question when the sample is too small. This essential book will enable social and behavioral science researchers to test their hypotheses even when the statistical model required for answering their research question is too complex for the sample sizes they can collect. The statistical models in the book range from the estimation of a population mean to models with latent variables and nested observations, and solutions include both classical and Bayesian methods. All proposed solutions are described in steps researchers can implement with their own data and are accompanied with annotated syntax in R. The methods described in this book will be useful for researchers across the social and behavioral sciences, ranging from medical sciences and epidemiology to psychology, marketing, and economics.

Download or read book Statistical Strategies for Small Sample Research written by Rick H. Hoyle and published by SAGE Publications. This book was released on 1999-03-30 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newer statistical models, such as structural equation modeling and hierarchical linear modeling, require large sample sizes inappropriate for many research questions or unrealistic for many research arenas. How can researchers get the sophistication and flexibility of large sample studies without the requirement of prohibitively large samples? This book describes and illustrates statistical strategies that meet the sophistication/flexibility criteria for analyzing data from small samples of fewer than 150 cases. Contributions from some of the leading researchers in the field cover the use of multiple imputation software and how it can be used profitably with small data sets and missing data; ways to increase statistical power when sample size cannot be increased; and strategies for computing effect sizes and combining effect sizes across studies. Other contributions describe how to hypothesis test using the bootstrap; methods for pooling effect size indicators from single-case studies; frameworks for drawing inferences from cross-tabulated data; how to determine whether a correlation or covariance matrix warrants structure analysis; and what conditions indicate latent variable modeling is a viable approach to correct for unreliability in the mediator. Other topics include the use of dynamic factor analysis to model temporal processes by analyzing multivariate; time-series data from small numbers of individuals; techniques for coping with estimation problems in confirmatory factor analysis in small samples; how the state space model can be used with surprising accuracy with small data samples; and the use of partial least squares as a viable alternative to covariance-based SEM when the N is small and/or the number of variables in a model is large.

Download or read book The Boston Renaissance written by Barry Bluestone and published by Russell Sage Foundation. This book was released on 2000-06-29 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume documents metropolitan Boston's metamorphosis from a casualty of manufacturing decline in the 1970s to a paragon of the high-tech and service industries in the 1990s. The city's rebound has been part of a wider regional renaissance, as new commercial centers have sprung up outside the city limits. A stream of immigrants have flowed into the area, redrawing the map of ethnic relations in the city. While Boston's vaunted mind-based economy rewards the highly educated, many unskilled workers have also found opportunities servicing the city's growing health and education industries. Boston's renaissance remains uneven, and the authors identify a variety of handicaps (low education, unstable employment, single parenthood) that still hold minorities back. Nonetheless this book presents Boston as a hopeful example of how America's older cities can reinvent themselves in the wake of suburbanization and deindustrialization.

Download or read book Sphingolipids Sphingolipidoses and Allied Disorders written by Bruno Volk and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text contains the scientific contributions to the Fourth International Symposium on Sphingolipids, Sphingo lipidoses and Allied Disorders held at the Kingsbrook Jewish Medical Center on October 25-27, 1971. These meetings were conducted under the auspices of the Isaac Albert Research Institute of the Kingsbrook Jewish Medical Center and the National Tay-Sachs and Allied Diseases Association, Inc. Four symposia, held in 1958, 1961, 1965 and 1971 were designed to gather the most relevant and innovative of the laboratory and field studies concerned with these hereditary disorders. The texts generated by these periodic meetings have mirrored the increasing absorption of the scientific community in the problems of sphingolipid metabolism. The first meeting in 1958 consisted of but twelve pre sentations, the majority emanating from local laboratories. The current sessions contain 48 scientific presentations by scientists from nine countries and demonstrate the increas ingly diversified techniques and approaches employed in the study of these diseases. Many of the authors, in exploring data on the mucopolysaccharidoses and leucodystrophies, as well as the sphingolipidoses, have given recognition to those biochemical areas held in common by these otherwise diverse disease processes. The problems of prevention and therapy of these diseases have been considered by some of the contributors. Laboratory screening procedures designed to detect carriers of the va rious lipidoses are now available and the experiences of some laboratories in this area are summarized within this volume. The prospective identification of heterozygotes may indeed become a powerful adjunct in genetic counseling.

Download or read book Scientific Protocols for Fire Investigation Third Edition written by John J. Lentini and published by CRC Press. This book was released on 2018-09-28 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Protocols for Fire Investigation, Third Edition focuses on the practical application of fundamental scientific principles to determine the causes of fires. Originally published in 2006, the First Edition was very well received by fire investigators and those who work with them. Since fire investigation is a rapidly evolving field—driven by new discoveries about fire behavior—the Second Edition was published in late 2012. This latest, fully updated Third Edition reflects the most recent developments in the field. Currently, serious research is underway to try to understand the role of ventilation in structure fires. Likewise, there is improved understanding of the kinds of errors investigators can make that lead to incorrect determinations of the causes of fires. In addition to the scientific aspects, the litigation of fire related events is rapidly changing, particularly with respect to an investigator's qualifications to serve as an expert witness. This book covers these latest developments and ties together the changing standards for fire investigations with the fundamental scientific knowledge presented in the early chapters of the book. The book is intended for those individuals who have recently entered the field of fire investigation, and those who are studying fire investigation with a plan to become certified professionals. In addition, professionals in the insurance industry who hire fire investigators will find this an invaluable resource. Insurance companies have sustained significant losses by hiring individuals who are not qualified, resulting in cases being settled or lost at a cost of millions. Insurance adjusters and investigators will learn to recognize quality fire investigations and those that are not up to today's standards. Lastly, this book is also for the many attorneys who litigate fire cases. Written with language and terms that make the science accessible even to the non-scientist, this new edition will be a welcome resource to any professional involved in fire and arson cases.
