Journal of Abnormal Psychology, 112, 545-557. Allison reviews approaches to modeling with missing values, and provides support for using full information maximum likelihood (FIML) and multiple imputation. Anderson, J. C., & Gerbing, D. W. (1988). Structural equation modeling in practice: A review and recommended two-step approach. Psychological Bulletin, 103(3), 411-423. Seminal citation for the establishment of an adequate measurement model before proceeding to a test of the structural model in a general SEM. Beauducel, A., & Herzberg, P. Y. (2006). On the performance of maximum likelihood versus means and variance adjusted weighted least squares estimation in CFA. Structural Equation Modeling, 13(2), 186-203. In addition to the Flora and Curran reference below, this article serves as a reference for the use of WLSMV with categorical data. Their simulations took into account the number of categories, the number of factors, and sample size. Bentler, P. M., & Mooijaart, A. (1989). Choice of structural model via parsimony: A rationale based on precision. Psychological Bulletin, 106(2), 315-317. A general rule in SEM is that when choosing between two competing models, the more parsimonious model is desirable. This article justifies the choice of the parsimonious model by demonstrating that parameter estimates are more precise in parsimonious models. Bollen, K. A. (2000). Modeling strategies: In search of the Holy Grail. Structural Equation Modeling, 7(1), 74-81. This article presents discusses different approaches to finding the correct number of factors in a measurement model. It provides support for the use of a “piecewise jigsaw technique,” which can be useful when complicated, multi-factor models are being tested. Bollen, K. A. (1989). Structural equations with latent variables. New York: John Wiley & Sons. Bollen’s book is a seminal and comprehensive source on virtually all aspects of SEM. If you plan to become a regular user of SEM, this book needs to be on your shelf. Boomsa, A. (2000). Reporting analyses of covariance structures, Structural Equation Modeling 7, 461-483.

C., Browne, M. W., & Sugawara, H. M. (1996). Power analysis and determination of sample size for covariance structure modeling. Psychological Methods, 1, 130-149. This article is a must-read for those interested in gaining a deeper understanding of power analysis using RMSEA. The tables can be used on their own to estimate power. (See also handout by Bowen on power.) MacCallum, R. C., Widaman, K. F., Zhang, S., & Hong, S. (1999). Sample size in factor analysis. Psychological Methods, 4(1), 84-99. The article demonstrates how sample size requirements for confirmatory factor analyses may vary based on the magnitude of factor loadings and the number of indicators loading on a factor. The point is that rules of thumb about how many cases are needed for analyses may not be valid. MacCallum, R. C., Browne, M. W., & Cai, L. (2006).

Version7.1 mplus language addendum.pdf. http://www.statmodel.com/download/Version7.1xLanguage.pdf: Part of this short addendum explains how to request tests of configural, metric, and scalar invariance in one line of code. The code can also be modified to allow tests of partial invariance 6 v.2, N.K. Bowen, 2014 if full invariance is not found. The code saves invariance tester a lot of coding because Mplus’ default is a constrained model, while it is easiest to start a series of invariance tests with an unconstrained model. Muthén, L.
