I teach “Modeling for Inference” which focuses on accurate and meaningful story telling with data science. Gone are the days with simple hypothesis tests and the over reliance on p-values. The Modeling for Inference course is a comprehensive and holistic statistical modeling course focusing on methods students can adapt and use to answer their own hypotheses.
