Multilevel modeling (two-levels) in R with 'lme4' package (May, 2019)

In this video, I provide a demonstration of several multilevel analyses using the 'lme4' package. Specifically, I test a random intercept model and two models containing fixed effects and levels 1 and 2. The data from the 'High School and Beyond' survey (found in the 'merTools' package).

THE VIDEO COVERS MUCH MORE DETAIL ON PERFORMING A VARIETY OF ANALYSES, INCLUDING TESTING AND PROBING CROSS-LEVEL INTERACTIONS. YOU WILL ALSO FIND SUPPLEMENTAL MATERIALS UNDER THAT VIDEO DESCRIPTION, SO BE SURE TO CHECK IT OUT AT https://youtu.be/8r9bUKUVecc For more examples of multilevel modeling using various programs, go here: https://sites.google.com/view/statistics-for-the-real-world/contents/multilevel-modeling-and-panel-regression
