How Shapley Values Work
Shapley values - and their popular extension, SHAP - are machine learning explainability techniques that are easy to use and interpret but the theory can be intimidating to learn. This post explores how Shapley values work - not by using cryptic formulae, but through code and simplified explanations.

RTutor - Talk to your data via AI
RTutor enables users to interact with data via natural language. After uploading a dataset, users can ask questions about or request analyses in plain English. The app generates and runs R code to answer the questions with plots and numeric results. It can also explain statistical concepts and help users decide which tests to use. It's experimental but looks like a good tool for learning.
