| exploratory factor analysis meaning: Exploratory Factor Analysis W. Holmes Finch, 2019-09-05 A firm knowledge of factor analysis is key to understanding much published research in the social and behavioral sciences. Exploratory Factor Analysis by W. Holmes Finch provides a solid foundation in exploratory factor analysis (EFA), which along with confirmatory factor analysis, represents one of the two major strands in this field. The book lays out the mathematical foundations of EFA; explores the range of methods for extracting the initial factor structure; explains factor rotation; and outlines the methods for determining the number of factors to retain in EFA. The concluding chapter addresses a number of other key issues in EFA, such as determining the appropriate sample size for a given research problem, and the handling of missing data. It also offers brief introductions to exploratory structural equation modeling, and multilevel models for EFA. Example computer code, and the annotated output for all of the examples included in the text are available on an accompanying website. |

| exploratory factor analysis meaning: Handbook of Applied Multivariate Statistics and Mathematical Modeling Howard E.A. Tinsley, Steven D. Brown, 2000-05-22 Multivariate statistics and mathematical models provide flexible and powerful tools essential in most disciplines. Nevertheless, many practicing researchers lack an adequate knowledge of these techniques, or did once know the techniques, but have not been able to keep abreast of new developments. The Handbook of Applied Multivariate Statistics and Mathematical Modeling explains the appropriate uses of multivariate procedures and mathematical modeling techniques, and prescribe practices that enable applied researchers to use these procedures effectively without needing to concern themselves with the mathematical basis. The Handbook emphasizes using models and statistics as tools. The objective of the book is to inform readers about which tool to use to accomplish which task. Each chapter begins with a discussion of what kinds of questions a particular technique can and cannot answer. As multivariate statistics and modeling techniques are useful across disciplines, these examples include issues of concern in biological and social sciences as well as the humanities. |

| exploratory factor analysis meaning: The SAGE Handbook of Quantitative Methodology for the Social Sciences David Kaplan, 2004-06-21 Quantitative methodology is a highly specialized field, and as with any highly specialized field, working through idiosyncratic language can be very difficult made even more so when concepts are conveyed in the language of mathematics and statistics. The Sage Handbook of Quantitative Methodology for the Social Sciences was conceived as a way of introducing applied statisticians, empirical researchers, and graduate students to the broad array of state-of-the-art quantitative methodologies in the social sciences. The contributing authors of the Handbook were asked to write about their areas of expertise in a way that would convey to the reader the utility of their respective methodologies. Relevance to real-world problems in the social sciences is an essential ingredient of each chapter. The Handbook consists of six sections comprising twenty-five chapters, from topics in scaling and measurement, to advances in statistical modelling methodologies, and finally to broad philosophical themes that transcend many of the quantitative methodologies covered in this handbook. |

| exploratory factor analysis meaning: Statistical Methods in Social Science Research S P Mukherjee, Bikas K Sinha, Asis Kumar Chattopadhyay, 2018-10-05 This book presents various recently developed and traditional statistical techniques, which are increasingly being applied in social science research. The social sciences cover diverse phenomena arising in society, the economy and the environment, some of which are too complex to allow concrete statements; some cannot be defined by direct observations or measurements; some are culture- (or region-) specific, while others are generic and common. Statistics, being a scientific method – as distinct from a ‘science’ related to any one type of phenomena – is used to make inductive inferences regarding various phenomena. The book addresses both qualitative and quantitative research (a combination of which is essential in social science research) and offers valuable supplementary reading at an advanced level for researchers. |

| exploratory factor analysis meaning: Poverty in the Philippines Asian Development Bank, 2009-12-01 Against the backdrop of the global financial crisis and rising food, fuel, and commodity prices, addressing poverty and inequality in the Philippines remains a challenge. The proportion of households living below the official poverty line has declined slowly and unevenly in the past four decades, and poverty reduction has been much slower than in neighboring countries such as the People's Republic of China, Indonesia, Thailand, and Viet Nam. Economic growth has gone through boom and bust cycles, and recent episodes of moderate economic expansion have had limited impact on the poor. Great inequality across income brackets, regions, and sectors, as well as unmanaged population growth, are considered some of the key factors constraining poverty reduction efforts. This publication analyzes the causes of poverty and recommends ways to accelerate poverty reduction and achieve more inclusive growth. it also provides an overview of current government responses, strategies, and achievements in the fight against poverty and identifies and prioritizes future needs and interventions. The analysis is based on current literature and the latest available data, including the 2006 Family Income and Expenditure Survey. |

| exploratory factor analysis meaning: An Introduction to Applied Multivariate Analysis with R Brian Everitt, Torsten Hothorn, 2011-04-23 The majority of data sets collected by researchers in all disciplines are multivariate, meaning that several measurements, observations, or recordings are taken on each of the units in the data set. These units might be human subjects, archaeological artifacts, countries, or a vast variety of other things. In a few cases, it may be sensible to isolate each variable and study it separately, but in most instances all the variables need to be examined simultaneously in order to fully grasp the structure and key features of the data. For this purpose, one or another method of multivariate analysis might be helpful, and it is with such methods that this book is largely concerned. Multivariate analysis includes methods both for describing and exploring such data and for making formal inferences about them. The aim of all the techniques is, in general sense, to display or extract the signal in the data in the presence of noise and to find out what the data show us in the midst of their apparent chaos. An Introduction to Applied Multivariate Analysis with R explores the correct application of these methods so as to extract as much information as possible from the data at hand, particularly as some type of graphical representation, via the R software. Throughout the book, the authors give many examples of R code used to apply the multivariate techniques to multivariate data. |
| exploratory factor analysis meaning: Practical Statistics for Data Scientists Peter Bruce, Andrew Bruce, 2017-05-10 Statistical methods are a key part of of data science, yet very few data scientists have any formal statistics training.

| exploratory factor analysis meaning: Encyclopedia of Quality of Life and Well-Being Research Alex C. Michalos, 2014-02-12 The aim of this encyclopedia is to provide a comprehensive reference work on scientific and other scholarly research on the quality of life, including health-related quality of life research or also called patient-reported outcomes research. Since the 1960s two overlapping but fairly distinct research communities and traditions have developed concerning ideas about the quality of life, individually and collectively, one with a fairly narrow focus on health-related issues and one with a quite broad focus. In many ways, the central issues of these fields have roots extending to the observations and speculations of ancient philosophers, creating a continuous exploration by diverse explorers in diverse historic and cultural circumstances over several centuries of the qualities of human existence. What we have not had so far is a single, multidimensional reference work connecting the most salient and important contributions to the relevant fields. Entries are organized alphabetically and cover basic concepts, relatively well established facts, lawlike and causal relations, theories, methods, standardized tests, biographic entries on significant figures, organizational profiles, indicators and indexes of qualities of individuals and of communities of diverse sizes, including rural areas, towns, cities, counties, provinces, states, regions, countries and groups of countries. |

Exploratory data analysis - using visualisations and multivariate techniques to explore datasets. Statistical inference - modern methods for testing hypotheses and computing confidence intervals. Predictive modelling - regression models and machine learning methods for prediction, classification, and forecasting. Simulation - using simulation techniques for sample size computations and evaluations of statistical methods. Ethics in statistics - ethical issues and good statistical practice. R programming - writing code that is fast, readable, and (hopefully!) free from bugs. No prior programming experience is necessary. Clear explanations and examples are provided to accommodate readers at all levels of familiarity with statistical principles and coding practices. A basic understanding of probability theory can enhance comprehension of certain concepts discussed within this book. In addition to plenty of examples, the book includes more than 200 exercises, with fully worked solutions available at: www.modernstatisticswithr.com. |

Substantive changes were made to the WAIS-IV from the WAIS-III leaving clinicians with questions as to how to use and interpret the measure effectively. Written by the creators of the new test, this book serves as the ultimate insider's guide to the new test, providing users with the kind of access to norms and data that would be unavailable to any subsequent book on clinical use of this measure. The book discusses the changes made between 3rd and 4th editions along with an FAQ and answers about use and interpretation. The reader is instructed how to interpret composite scores, and everything needed to use and interpret two entirely new composite scores: the General Ability Index (GAI), and the Cognitive Proficiency Index (CPI). This information does NOT appear in the manual accompanying the test. The second section of the book focuses on WAIS–IV use and interpretation with special clinical applications and populations, including with multicultural clients, in neuropsychological settings, with individuals experiencing psychological disorders, and with older adults. The editors and chapter authors have exclusive access to proprietary WAIS–IV data to run advanced analyses and provide information beyond what is offered in the WAIS-IV manual. - Provides practical advice on scoring and administration - Facilitates understanding WAIS-IV use with special populations - Describes use of the WAIS-IV with WMS-II |
