Highlights the critical questions to ask about synthesis methodology at each step and the identification of "best practices" - Contains two new chapters giving expanded treatments of gathering information from studies and interpreting the evidence from a research synthesis - Provides completely updated material on techniques for searching the literature with an emphasis on new technologies and the Internet - Includes a discussion of recent advances and issues in meta-analysis statistical techniques - Offers new standards for reporting meta-analyses results - Incorporates new research syntheses drawn from the fields of education, social/developmental psychology, and health throughout the book

Mathematical models and methods in the economic theory are very various. They are as follows: econometrics, the game theory, operation research, nonlinear and chaotic dynamics and many other aspects as well. The book will be interesting only to those who are already familiar with corresponding tasks as well as to students at all levels specializing in economic dynamics, in decision-making methods, in forecasting effects of management and in the analysis of interaction of economic agents. In terms of the most interesting and new models of economic dynamics, the authors emphasize multidimensional nonlinear systems of the differential equations of Lotka-Volterra type. .

The Teaching Writing series publishes user-friendly writing guides penned by authors with publishing records in their subject matter. Infused with multidisciplinary examples, humor, and a healthy dose of irreverence, Fallon helps emerging researchers successfully navigate the intellectual and emotional challenges of writing quantitative research reports.

This book contains a short presentation of the most basic aspects of probability theory. As a result, it should come in handy and help students grasp the main concepts of the discipline as well as acquire a basic probabilistic vocabulary, thus capturing at least the flavour of possible relevant applications. The book includes a sketch of von Neumann - Morgenstern utility theory, which is useful per se as well as being an enlightening bridge between probability and decision theories. The book also provides a substantial set of exercises with solutions. Book jacket.

This book is intended as an introduction to Probability Theory and Mathematical Statistics for students in mathematics, the physical sciences, engineering, and related fields.

A Primer on Effect Sizes, Simple Research Designs, and Confidence Intervals was designed to help individuals learn to calculate effect sizes for their research designs. Effect sizes allow a clinician or researcher to determine the effect of a treatment. For example, an effect size of zero would indicate that the treatment had no effect, but generally effect sizes allow researchers to see the degree of effect of some treatment or intervention. Often, researchers and clinicians are not aware that effect sizes are connected to research designs.

This accessible and easy-to-read book provides many examples to illustrate diverse topics in probability and statistics, from initial concepts up to advanced calculations.

The American Community Survey (ACS) was conceptualized as a replacement to the census long form, which collected detailed population and housing data from a sample of the U.S. population, once a decade, as part of the decennial census operations. The long form was traditionally the main source of socio-economic information for areas below the national level. The data provided for small areas, such as counties, municipalities, and neighborhoods is what made the long form unique, and what makes the ACS unique today. Since the successful transition from the decennial long form in 2005, the ACS has become an invaluable resource for many stakeholders, particularly for meeting national and state level data needs. However, due to inadequate sample sizes, a major challenge for the survey is producing reliable estimates for smaller geographic areas, which is a concern because of the unique role fulfilled by the long form, and now the ACS, of providing data with a geographic granularity that no other federal survey could provide.

Outlines the essential statistical methods for survey design and analysis, while also exploring techniques that have developed over the past decade. Guides the reader through sampling designs, problems of missing data, statistical analysis of multistage sampling data, and non response and post stratification adjustment procedures; a chapter on telephone sampling, with coverage of declining response rates, the creation of "do not call" lists, and the growing use of cellular phones

This second volume of the series includes applications of some powerful forecasting approaches with a focus on fuzzy time series methods. Chapters integrate these methods with concepts such as neural networks, high order multivariate systems, deterministic trends, distance measurement and much more. The chapters are contributed by eminent scholars and serve to motivate and accelerate future progress while introducing new branches of time series forecasting. This book is a valuable resource for MSc and PhD students, academic personnel and researchers seeking updated and critically important information on the concepts of advanced time series forecasting and its applications.

Data Mining: A Tutorial-Based Primer, Second Edition provides a comprehensive introduction to data mining with a focus on model building and testing, as well as on interpreting and validating results. The text guides students to understand how data mining can be employed to solve real problems and recognize whether a data mining solution is a feasible alternative for a specific problem. Fundamental data mining strategies, techniques, and evaluation methods are presented and implemented with the help of two well-known software tools. Several new topics have been added to the second edition including an introduction to Big Data and data analytics, ROC curves, Pareto lift charts, methods for handling large-sized, streaming and imbalanced data, support vector machines, and extended coverage of textual data mining. The second edition contains tutorials for attribute selection, dealing with imbalanced data, outlier analysis, time series analysis, mining textual data, and more.

Introduction to Time Series Analysis and Forecasting presents the time series analysis branch of applied statistics as the underlying methodology for developing practical forecasts, and it also bridges the gap between theory and practice by equipping readers with the tools needed to analyze time-oriented data and construct useful, short- to medium-term, statistically based forecasts.

Surveys have a number of different steps that need to be addressed. Designing surveys requires you to: Set objectives for information collection; Design your research around those objectives; Prepare a reliable survey instrument; Manage and code the instrument; Analyse data; Report results. Sections 1 and 2 of this ebook are devoted primarily to the construction of the research question and its importance in influencing the design of the survey. Sections 3, 4, 5 and 6 concentrate on the development of the questionnaire or survey instrument. Section 7 ensures that the survey instrument is valid and reliable. Finally, Section 8 considers the layout of your survey questionnaire.

If you want to know what your employees or customers think, a survey may be the answer. But surveys provide valuable and accurate data only when they are conducted correctly. This issue of TD at Work will help you design and administer effective surveys. "Surveys From Start to Finish" offers tips for determining when to conduct a survey, what type of survey to use, whom to survey, what questions to ask, and how to get the information you need.
