About two years ago, I <a href="https://www.rdatagen.net/post/2022-11-01-modeling-secular-trend-in-crt-using-gam/" target="_blank">described</a> a model for estimating a treatment effect in a cluster-randomized stepped wedge trial. We used a generalized additive model (GAM) with site-specific splines to account for general time trends, implemented using the <code>mgcv</code> package. I’ve been interested in exploring a Bayesian version of this model, but hadn’t found the time to try - until I happened to pose this simple question to ChatGPT:</p>
