The recording from UseR Oslo's meetup 28/05/2020, https://www.meetup.com/OslouseRGrou...

Description:

When working with data, we often want to create models to predict future events, but we also want an even deeper understanding of how our data is causally connected or structured. In this workshop, we explored the connectedness of data using structural equation modeling (SEM) with the {lavaan} package.

The packages used in this video is lavaan, semPlot, MPsychoR and corrplot. We recommend that you have these packages installed prior to the starting if you want to follow activly. Below is a line of code you can use.

install.packages(c("lavaan", "semPlot", "MPsychoR", "corrplot"))

The speaker, Ronny Scherer, received his PhD from HumboldtUniversität zu Berlin in 2012, and is currently working at the Centre for Educational Measurement, University of Oslo (CEMO). His research and teaching cover structural equation modeling, metaanalysis, computerbased assessments, and multilevel analysis. Ronny is coordinating the Measurement Models course at CEMO.
