Thank you for linking us under this thread, Shira! I enjoyed reading the discussion. It's worth considering in more detail how Prediction-Powered Inference borrows from older ideas, such as the GREG estimate--and how PPI differs from, for instance, Bootstrap sampling that uses just one data source.

Congratulations, Chagai! Wishing you the best—though we’ll miss the causal inference powerhouse at @pascl-stanford.bsky.social. Good luck!
