Paul Yarnold

Hi, Amy!

Here is an article that may be perfect for your project!

Stalans, L.J., Yarnold, P.R., Seng, M., Olson, D.E., & Repp, M. (2004). Identifying three types of violent offenders and predicting violent recidivism while on probation: A classification tree analysis. Law & Human Behavior, 28, 53-271.

Thanks, Paul! This seems more useful for making predictions rather than comparing means?

Welcome, Amy

Sorry, I don't remember the study, nor do I have a copy of the paper. I think it is safe to hypothesize that it explains the logic and methodology for measuring and comparing recidivism rates between three different cohorts, viewed from a Criminal Justice perspective--which is not my area.

Have you reviewed the literature in recidivism, to see how recidivism is measured and compared between groups and/or across time? That is your best bet to find an example that is perfect for your application.

Good luck!
