Multilevel Analysis Techniques and Applications, Third Edition
We just submitted the page proofs of the 3rd edition of the book Multilevel Analysis Techniques and Applications 🙂 Almost ready now… It is expected to come out this September. That is, if we are able to finish all the other documents on time… From…
The relationship between tics, OC, ADHD and autism symptoms
Gilles de la Tourette’s syndrome (GTS) is a disorder in which obsessive-compulsive (OC), Attention Deficit Hyperactivity Disorder (ADHD) and autism symptoms occur in up to 60% of patients, suggesting shared etiology.
Collinear Latent Variables in Multilevel Confirmatory Factor Analysis: A Comparison of Maximum Likelihood and Bayesian Estimation
Because variables may be correlated in the social and behavioral sciences, multicollinearity might be problematic. This study investigates the effect of collinearity manipulated in within and between levels of a two-level confirmatory factor analysis by Monte Carlo simulation.
A checklist for testing measurement invariance
The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor model that measures a latent concept, we can assure that comparisons that are made on the latent variable are valid across groups or time.
