The videos, links, and SAS code below are designed to allow SAS users to teach themselves how to plan, run, and interpret latent class analysis (LCA). This page is designed for users of all levels to be able to jump in wherever they need information. Within each section, there may be different ways to get the same information (e.g., watching a video, listening to a podcast, or running a SAS exercise). Users who possess basic familiarity with a given subject may want to download and run SAS code immediately. Users who are new to a subject may want to watch a video before running the relevant code.
All materials are designed for researchers who are new to LCA but who do have some familiarity with SAS. In other words, this is an LCA tutorial, not a SAS tutorial.
If you want to follow along with the examples below, you will need a computer that runs Windows with an installation of SAS 9.2 or higher. You will also need to download PROC LCA. We also offer the LCA Plugin for Stata users, but these materials focus primarily on our SAS procedure.
