This course will introduce students to three forms of growth curve analysis: latent growth curves, latent growth trajectory analysis, and growth mixture models. This class of statistical methods provides a powerful set of tools to describe changes in a population. Students will be taught the differences between types of models, when to apply the correct model, and how to interpret results. Simple simulations of analyses will be conducted in R.

By the end of the course, participants will be able to:

1. Identify the proper modeling technique for analytical questions regarding change
2. Describe how latent growth, latent growth trajectory analysis, and growth mixture models are related to, and different from, one another
3. Interpret results all three types of growth models
4. Clearly articulate the benefits, assumptions, and shortcomings of growth trajectory analysis

Experience with longitudinal data will be beneficial.

Michael Bader, PhD

Michael Bader studies how cities and neighborhoods have evolved since the height of the Civil Rights Movement and how these changes affect racial health inequality. Dr. Bader uses a variety of methods, including developing methodological tools that combine survey data with “big data” to study neighborhood environments.

Dr. Bader is an associate professor of sociology at Johns Hopkins University and an investigator with the Built Environment and Health project. Before joining Johns Hopkins, Dr. Bader was on the faculty of at American University where he was associate director of the Metropolitan Policy Center and Director of the DC Area Survey. He received his Ph.D. in sociology from the University of Michigan his B.A. in architecture and art history from Rice University/
