Just tried out the {acquaint} #rstats package for the first time, a tool that connects your R sessions to Claude via MCP. After setting up my config and running acquaint::mcp_session(), Claude took a look at my data, and started giving me analysis suggestions. Awesome!

This looks a must read for those interested in triple differences (DDD) designs. It shows that the standard way many estimate DDD is wrong. It shows why and gives you tools that work with covariates and staggered adoption. Bonus: free R package.
