Growth Curve Analysis Workshop



These are slides from a two-day Growth Curve Analysis (GCA) workshop given at Georg-Elias-Müller Institute for Psychology in Göttingen in March 2018. The purpose of the workshop was to provide a hands-on introduction to using GCA to analyze longitudinal or time course data, with a particular focus on eye-tracking data. The workshop was conducted in R (and RStudio) using the following packages:
