Adam N. Glynn; Miguel R. Rueda; Julian Schuessler – Sociological Methods & Research, 2024
Post-instrument covariates are often included as controls in instrumental variable (IV) analyses to address a violation of the exclusion restriction. However, we show that such analyses are subject to biases unless strong assumptions hold. Using linear constant-effects models, we present asymptotic bias formulas for three estimators (with and…

David Goretzko; Karik Siemund; Philipp Sterner – Educational and Psychological Measurement, 2024
Confirmatory factor analyses (CFA) are often used in psychological research when developing measurement models for psychological constructs. Evaluating CFA model fit can be quite challenging, as tests for exact model fit may focus on negligible deviances, while fit indices cannot be interpreted absolutely without specifying thresholds or cutoffs.…

Seide, Svenja E.; Jensen, Katrin; Kieser, Meinhard – Research Synthesis Methods, 2020
The performance of statistical methods is often evaluated by means of simulation studies. In case of network meta-analysis of binary data, however, simulations are not currently available for many practically relevant settings. We perform a simulation study for sparse networks of trials under between-trial heterogeneity and including multi-arm…

Parsons, Eric; Koedel, Cory; Tan, Li – Journal of Educational and Behavioral Statistics, 2019
We study the relative performance of two policy-relevant value-added models--a one-step fixed effect model and a two-step aggregated residuals model--using a simulated data set well grounded in the value-added literature. A key feature of our data generating process is that student achievement depends on a continuous measure of economic…

Quiroz, Waldo; Rubilar, Cristian Merino – Chemistry Education Research and Practice, 2015
This study develops a tool to identify errors in the presentation of natural laws based on the epistemology and ontology of the Scientific Realism of Mario Bunge. The tool is able to identify errors of different types: (1) epistemological, in which the law is incorrectly presented as data correlation instead of as a pattern of causality; (2)…

Cramer, Elliot M.; Appelbaum, Mark I. – Review of Educational Research, 1978
Assuming conditional normality and independence, standard estimation and hypothesis testing procedures for regression coefficients are the same whether using fixed x values, random x values or mixed fixed and random values. Contrary to Sockloff's suggestion, polynomial regression is useful with either fixed or random models. (See EJ 142 050). (CP)

Tinsley, Howard E. A. – Journal of Vocational Behavior, 2000
A research review supports the validity of the person-environment fit (PEF) model in vocational psychology; however, sampling inadequacies have influenced results. One PEF example, Holland's hexagonal model, is unsupported due to lack of commensurate measurement; most hexagonal congruence indices are invalid. (Contains 110 references.) (SK)

McPhee, Robert D.; Babrow, Austin – Communication Monographs, 1987
Presents a table of cases requiring causal modeling or an equivalent technique. Reviews nine years of published research in communication journals to assess the adequacy of analysis in these situations. Offers standards for the conduct and reporting of causal modeling along with a review of their use in published causal modeling. (NKA)

Bekker, Paul A.; de Leeuw, Jan – Psychometrika, 1987
Psychometricians working in factor analysis and econometricians working in regression with measurement error in all variables are both interested in the rank of dispersion matrices under variation of diagonal elements. This paper reviews both fields; points out various small errors; and presents a methodological comparision of factor analysis and…

Chatterjee, Sangit; Yilmaz, Mustafa – Applied Psychological Measurement, 1992
The importance of regression diagnostics in detecting influential data points is discussed, and five statistics are recommended for the applied researcher. The suggested diagnostics were used on a dataset of 24 subjects, and effects were analyzed. Colinearity-based diagnostics and diagnostics for a variety of procedures are discussed. (SLD)

Newman, Isadore – 1988
The nature and appropriate application of the technique of multivariate analysis are discussed. More specifically, the intent of the paper is to demystify and explain the use of multivariate analysis as well as provide guidelines for selection of the most effective statistics for use in specific situations. For the purpose of this paper, the term…

Campbell, Richard T. – Sociology of Education, 1983
This paper analyzes Jencks et al's (1983) and Hauser et al's (1983) reports of their research on the Wisconsin status attainment model. For example, the meaning and interpretation of "unmeasured" family background are discussed and the charge that the status attainment model ignores social structure is examined. (Author/IS)

Jencks, Christopher; And Others – Sociology of Education, 1983
Data from Project Talent are utilized to assess the representativeness of the samples used in the Wisconsin and the Exploration in Equality of Opportunity (EEO) surveys. Adequacy of the measures of academic aptitude and aspiration used in the surveys are examined, and problems with the Wisconsin model are briefly discussed. (RM)

Hauser, Robert M.; And Others – Sociology of Education, 1983
An analysis of the Wisconsin model of achievement asks how powerful this model is in accounting for social influences, aspirations, and attainment when measurement error is taken into account. Revised estimates show support for the Wisconsin model. A revised model is even more powerful for explaining educational and occupational achievement.…
