Mplus is a useful tool for conducting SEM-related analyses from start to finish. DSEM and RDSEM Theory The following papers discuss multilevel time series analysis modeling and estimation: Asparouhov, T. Moderation modeling with latent variables and dummy Xs may be more easily done via multiple-group modeling (3 groups in your case) where key parameters vary across the groups. We use these codes to represent various multilevel moderation hypotheses, consistent with the A basic knowledge of the Mplus language and the ideas behind SEM/Path Analysis will be advantageous to participants. 2 and slide 43 of the Topic 7 course handout for details. The data sets that we can share are also included. In both intervention and observational research, mediation analyses are central to testing these theories because they describe how or why an effect occurs. 2022. & Bryk, 1986) and moderation and mediation (e. Instead of mean centering all indicators in Mplus, I centered the indicators for latent independent variables in R first (x1 through x6) and formed the latent interaction product terms there (i. ). Model 1a (latent variable version): 1 moderator [BASIC MODERATION] Example Variables: 1 latent predictor X measured by 4 observed variables X1-X4, 1 latent moderator W measured by 4 observed variables W1-W4, 1 latent outcome Y measured by 4 observed variables Y1-Y4. When ignored, a non-zero 1i residual leads to a heteroscedastic residual in the regression of m on x and z x, that is, a residual that varies with the x values. Regression and mediation analysis using Mplus. I run occasional public courses on the basics of Mplus and on testing mediation, moderation and moderated-mediation models using Mplus or SPSS, and also offer these on an inhouse basis - Continuous Moderation Example (Mplus) A subsequent handout (“Simple Slopes for Exploring a Significant Interaction in SEM”) will illustrate simple slopes tests and plotting.
