Building up to a hierarchical model: Coronavirus testing
Using a fitted model for decision analysis: Mixture model for time series competition
Posterior predictive checking: Stochastic learning in dogs
Incremental development and testing: Black cat adoptions
Debugging a model: World Cup football
Leave-one-out cross validation model checking and comparison: Roaches
Model building and expansion: Golf putting
Model building with latent variables: Markov models for animal movement
Model building: Time-series decomposition for birthdays
Models for regression coefficients and variable selection: Student grades
Sampling problems with latent variables: No vehicles in the park

Someone emailed me to ask if my lectures are online anywhere, so yes here is the link to most recent lectures. These lectures are free and free of Cyclospora

We've added to the website a free PDF of the Bayesian Workflow book (for non-commercial purposes, like research and exorcism). We put so much work into this book, hope you all find value in it. avehtari.github.io/Bayesian-Workf…

The Bayesian Workflow book is out in print now, just in time to distract you from *gestures all around*. Some links below to code and other resources:
