# Applied Statistics for Educational Researchers DUH165

This course is organized in several workshops and will introduce in structural equations models with growth curve modeling and autoregressive dynamic structural equations models as special applications. We will use the software packages Mplus and R.

Content

In the seminar, we will introduce Confirmative Factor Analysis (CFA) and Structural Equations Modelling (SEM) and see how Latent Growth Curve Models (LGCMs) can be understood as an extension of SEM with intercepts and/or slopes being modelled as latent variables, first as an unconditional latent curve model. We will then look at conditional LGCMs (including mediation models, cross-lagged models, hierarchical/multilevel models), and comparison of (latent) groups with different approaches of testing measurement invariance, also in the Bayesian SEM framework. This will be extended to Dynamic Structural Equation Models with autoregressive slopes (DSEM), i.e. accounting for the influence of the respective previous time points on the outcome variable (time-lagging). Those models are important to analyze intensive longitudinal data, where many observations are nested in individuals. In contrast to latent growth modelling, borrowing logic from time-series analyses DSEM is interested in the dynamics over time, in terms of autoregressive associations between the same variable at Times T (concurrent time-point) and T-1 (the previous time-point), and cross-lagged associations between variables between T and T-1. Such models are possible to implement using Maximum Likelihood with user specified lagged variables. More complex models (e.g., multiple random slopes) are possible to implement using the Bayesian estimator in Mplus.

The working format is a blending of lectures, group discussions, and hand-on analyses in Mplus/R. The last session on DSEM will be additionally streamed as a webinar and is open for a wider audience (no credits are awarded for the DSEM-webinar).

Instructors: Ulrich Dettweiler (UiS), Knud Knudsen (UiS), Thormod Idsøe (NUBU, UiS), Lars-Erik Malmberg (Oxford University)

Required prerequisite knowledge
None
Recommended prerequisites
Know your project and the research questions thoroughly. Get yourself acquainted with MPlus and/or R prior to the course so that you feel competent to prepare the data for import in Mplus, and know some basic syntax (chapters 1 + 2 in Muthén & Muthén). Have some datasets prepared in the right format (.dat) for MPlus or .csv in R.
