Raykov, Tenko; Marcoulides, George A. – Structural Equation Modeling, 2001
Outlines a covariance structure analysis approach to the study of parameter trends. Uses the program RAMONA to illustrate the method by fitting a corresponding confirmatory factor analysis model to correlational data from a study involving several psychometric tests and fluid intelligence tasks.

Raykov, Tenko – Structural Equation Modeling, 2004
A widely and readily applicable covariance structure modeling approach is outlined that allows point and interval estimation of scale reliability with fixed components. The procedure employs only linear constraints introduced in a congeneric model, which after reparameterization permit expression of composite reliability as a function of…

Lei, Pui-Wa; Dunbar, Stephen B. – Structural Equation Modeling, 2004
The primary purpose of this study was to examine relative performance of 2 power estimation methods in structural equation modeling. Sample size, alpha level, type of manifest variable, type of specification errors, and size of correlation between constructs were manipulated. Type 1 error rate of the model chi-square test, empirical critical…

Conroy, David E.; Metzler, Jonathan N.; Hofer, Scott M. – Structural Equation Modeling, 2003
Studied the meaning of Performance Failure Appraisal Inventory (PFAI; Conroy and others, 2002) by evaluating the comparability of PFAI factor structure over repeated assessments and the stability of the subscales over relatively brief intervals. Results for 356 college students generally show high stability for PFAI scores in long and short forms.…

Beron, Kurt J.; Farkas, George – Structural Equation Modeling, 2004
Oral language skills and habits may serve as important resources for success or failure in school-related tasks such as learning to read. This article tests this hypothesis utilizing a unique data set, the original Woodcock-Johnson Psycho-Educational Battery-Revised norming sample. This article assesses the importance of oral language by focusing…
