What is a matrix in LISREL?
• What is a matrix in Amos? • How does one test for modifier or covariate control variables in a structural model? • How do you handle before-after and other repeated measures data in SEM? • How do you use crossproduct interaction terms in SEM? • If I run a SEM model for two subgroups of my sample, can I compare the path coefficients? • How and why should I model the mean structure of a model, not just covariance? • Should one standardize variables prior to structural equation modeling, or use standardized regression coefficients as an input matrix? • What do I do if I don’t have interval variables? • What is a “Heywood case”? • What are “replacing rules” for equivalent models? • Does it matter which statistical package you use for structural equation modeling? • What is a “structural equation model”? A structural equation mode is a complete path model which can be depicted in a path diagram. It differs from simple path analysis in that all variables are latent variables measured by mu
