This document is an informal introduction to—and a subsequent literature review of—[residual] dynamic structural equation modeling ([R]DSEM) of (intensive) longitudinal data. Although [R]DSEM is mostly applied to multi-level problems wherein the within- and between-person differences are modeled, here I assume these sources of variations can be disentangled. Then I will demonstrate how a simple, non-hierarchical, case of such models can be implemented using R package lavaan. This post is not complete yet, as of 29 Dec 2019.
