Design, estimate, validate, and write up a regression discontinuity analysis, in both the continuity and local-randomization frameworks, with the full falsification battery and a refusal rule for designs that fail validation.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Regression discontinuity An opinionated RD workflow grounded in a read canon (references/canon.md): the Cattaneo-Titiunik Annual Review of Economics survey and its applied companion, the Cattaneo-Keele-Titiunik guide, which includes a real failed design this skill uses as its refusal template.

The skill stops at the four stop points in ../causal-design/references/shared-rules.md (section "Stop points") and puts each choice to the user. Current as of 2026-10-09; refresh per shared-rules (../causal-design/references/shared-rules.md, section "Refresh path"). Nothing enters the canon without the user's approval. ## Design shapes and the case that anchors each Each canonical case is a precedent a methods section can cite; details.md says what each teaches. | Design shape | Canonical case | Marketing analogue | What kills it | |---|---|---|---| | Age or tenure eligibility rule | Card, Dobkin, Maestas 2008 | trial expiry, anniversary status rolloff | something else switches at the same threshold | …

How to install
mdr add ericluo04/claude-academic-workflow/rdd@sha256:a0050b9df838085cThe line at the top of this page pins the label git:20261009.3f6ab46, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
