CausalVerify - Regression Discontinuity: leaderboard
The regression-discontinuity scenarios of CausalVerify (Zhang et al., 2026), 22 synthetic datasets with a known design. As in the full benchmark, the model writes R code from a research question, a data description and a preview of the data, the code is executed, and the treatment effect it prints must fall within 50 percent relative error of a canonical estimator run on the same data; pass rate in percent with one attempt per scenario, higher is better.
Metric: Execution-grounded pass rate (%; L2b+ over the 22 regression-discontinuity scenarios; the model writes R code for a fixed-seed synthetic scenario from the research question, data description and a preview of the realised CSV; the code is executed and passes when the treatment-effect estimate it reports (read by a Claude Haiku 4.5 coefficient-extraction judge, event-study windows mapped to the canonical scale) is within 50% relative error of a canonical estimator applied to the same realised data; single-shot; the printed passes/22 count is read and converted to percent).
