Statistical Approaches to Measurement Invariance
Author: Roger E. Millsap
Publisher: Routledge
ISBN: 113676111X
Category : Psychology
Languages : en
Pages : 364
Book Description
This book reviews the statistical procedures used to detect measurement bias. Measurement bias is examined from a general latent variable perspective so as to accommodate different forms of testing in a variety of contexts including cognitive or clinical variables, attitudes, personality dimensions, or emotional states. Measurement models that underlie psychometric practice are described, including their strengths and limitations. Practical strategies and examples for dealing with bias detection are provided throughout. The book begins with an introduction to the general topic, followed by a review of the measurement models used in psychometric theory. Emphasis is placed on latent variable models, with introductions to classical test theory, factor analysis, and item response theory, and the controversies associated with each, being provided. Measurement invariance and bias in the context of multiple populations is defined in chapter 3 followed by chapter 4 that describes the common factor model for continuous measures in multiple populations and its use in the investigation of factorial invariance. Identification problems in confirmatory factor analysis are examined along with estimation and fit evaluation and an example using WAIS-R data. The factor analysis model for discrete measures in multiple populations with an emphasis on the specification, identification, estimation, and fit evaluation issues is addressed in the next chapter. An MMPI item data example is provided. Chapter 6 reviews both dichotomous and polytomous item response scales emphasizing estimation methods and model fit evaluation. The use of models in item response theory in evaluating invariance across multiple populations is then described, including an example that uses data from a large-scale achievement test. Chapter 8 examines item bias evaluation methods that use observed scores to match individuals and provides an example that applies item response theory to data introduced earlier in the book. The book concludes with the implications of measurement bias for the use of tests in prediction in educational or employment settings. A valuable supplement for advanced courses on psychometrics, testing, measurement, assessment, latent variable modeling, and/or quantitative methods taught in departments of psychology and education, researchers faced with considering bias in measurement will also value this book.

Experimental Design for Formulation
Author: Wendell F. Smith
Publisher: SIAM
ISBN: 9780898718393
Category : Science
Languages : en
Pages : 386
Book Description
Many products, such as foods, personal-care products, beverages, and cleaning agents, are made by mixing ingredients together. This book describes a systematic methodology for formulating such products so that they perform according to one's goals, providing scientists and engineers with a fast track to the implementation of the methodology. Experimental Design for Formulation contains examples from a wide variety of fields and includes a discussion of how to design experiments for a mixture setting and how to fit and interpret models in a mixture setting. It also introduces process variables, the combining of mixture and nonmixture variables in a designed experiment, and the concept of collinearity and the possible problems that can result from its presence. Experimental Design for Formulation is a useful manual for the formulator and can also be used by a resident statistician to teach an in-house short course. Statistical proofs are largely absent, and the formulas that are presented are included to explain how the various software packages carry out the analysis. Many examples are given of output from statistical software packages, and the proper interpretation of computer output is emphasized. Other topics presented include a discussion of an effect in a mixture setting, the presentation of elementary optimization methods, and multiple-response optimization wherein one seeks to optimize more than one response.

The Quality of Measurements
Author: A.E. Fridman
Publisher: Springer Science & Business Media
ISBN: 1461414784
Category : Technology & Engineering
Languages : en
Pages : 222
Book Description
This monograph and translation from the Russian describes in detail and comments on the fundamentals of metrology. The basic concepts of metrology, the principles of the International System of Units SI, the theory of measurement uncertainty, the new methodology of estimation of measurement accuracy on the basis of the uncertainty concept, as well as the methods for processing measurement results and estimating their uncertainty are discussed from the modern position. It is shown that the uncertainty concept is compatible with the classical theory of accuracy. The theory of random uncertainties is supplemented with their most general description on the basis of generalized normal distribution; the instrumental systematic errors are presented in connection with the methodology of normalization of the metrological characteristics of measuring instruments. The information about modern systems of traceability is given. All discussed theoretical principles and calculation methods are illustrated with examples.

ISBN: 0443217688
Category : Psychology
Languages : en
Pages : 342
Book Description
A Practical Guide to Functional Assessment and Treatment for Severe Problem Behavior discusses how to utilize functional assessment and function-based treatment for patients with severe problem behaviors. The book begins by defining problem behavior, contrasting functional and structural definitions, and clearly reviewing the term "severe". The second section, Functional Assessment of Problem Behavior, reviews three different assessments in detail, providing sample questionnaires, methods for interviewing and brief bonus videos. The third section, Function-Based Treatments, outlines three main treatment options, including comprehensive and trauma-informed strategies and outline information on collecting, graphing, and analyzing treatment data. The final section, Promoting Sustainability and Compassionate Care will review strategies to implement these assessments and treatments in a culturally relevant and compassionate way. - Details various examples of indirect assessments methods, including interviews and questionnaires - Addresses the integration and testing of hypotheses from indirect and descriptive assessments into functional analyses - Reviews treatments based on a trauma-informed framework - Outlines common ethical issues, including strategies to use when function-based treatments do not work and the management of restrictive practices - Includes bonus brief vignettes to illustrate procedures and assessments
