lavaangui : A Web-Based Graphical Interface for Specifying Lavaan Models by Drawing Path Diagrams

Structural Equation Modeling A Multidisciplinary Journal, vol. 32, pp. 1077–1088

Abstract

Path diagrams facilitate the specification of Structural Equation Models because drawing them is often faster and less error-prone than specifying a model using equations or matrix algebra. Despite this, there are very few free and open-source programs that allow model specification through path diagrams. To address this gap, this paper introduces the web application lavaangui, which is available at https://lavaangui.org. lavaangui is a graphical user interface that allows specifying lavaan models by drawing path diagrams. Additionally, it can be installed as an R package and then also supports creating interactive path diagrams from lavaan models specified in R. This paper presents a tutorial on using lavaangui.
