The LCAKB’s Code Repository is designed to be a “one-stop shop” to download sample code for latent class models. Many of the code examples come from projects and workshops conducted by Drs. Bethany Bray, John Dziak, and Stephanie Lanza when they were investigators at The Methodology Center at Penn State and supported in part by National Institute on Drug Abuse Center of Excellence awards from 1996-2021 (P50 DA039838 and P50 DA010075). In addition, many of the code examples come from the work of their collaborators and trainees, including those supported by the Prevention and Methodology Training Program, a National Institute on Drug Abuse Training Program (T32 DA017629).
Below you will find a list of all available models and code “snippets.” You can use the filters on the sidebar to narrow down the models for which you are looking. The LCAKB Code Repository is under active development and is currently being expanded. New models and code snippets will be published soon. Please sign up to our mailing list below to be informed of when they are published. If you would like to contribute a piece of code to help your fellow researchers, please email Dr. Bethany Bray at firstname.lastname@example.org.
