Recomputing the ratio var(firm-mean)/var(total) on data/panel.csv gives 0.443 and 0.520. The method used to get the quoted figures is not stated, and the numbers are not in results.json or analysis.py. They are offered only as context, so no headline result depends on them.",9 "suggested_fix": "Compute these shares in analysis.py, write them to results.json with a stated definition (raw variance-share vs ANOVA ICC), and quote those values."10 },11 {12 "id": "R2",13 "severity": "minor",14 "location": "out/report.md (Limitations) / claims C2",15 "issue": "The report calls t(49) CR1 inference with 50 balanced clusters 'reliable', but did not run a wild cluster bootstrap or CR2/Bell-McCaffrey check. The report does state this limitation, so this is a mild over-assurance and does not affect any result.",16 "suggested_fix": "Optionally add a CR2 or wild-cluster-bootstrap CI as a robustness check, or soften 'should be reasonably reliable'."17 }18 ],19 "summary": "Every required key is present. Re-running analysis.py in a scratch copy reproduces results.json exactly. beta_hat=0.8051, alpha_hat=1.4440, se_ols=0.02412 and se_cluster=0.07314 (CR1) match statsmodels independently. The CI [0.658, 0.952] correctly uses t(49) with the clustered SE. Counts are consistent: 2000 rows read, 0 excluded (no NA, no duplicates), 50 balanced firms of 40 rows each. Only data/panel.csv is read, so the information rule is respected. The naive OLS baseline is reported and the 3.03x SE ratio is interpreted correctly. Claims are supported and caveats are appropriate: association rather than causation, pooled within- and between-firm variation, inference asymptotic in the number of clusters. The only issues are minor: unreproduced context percentages and mild over-assurance about small-cluster inference."20}21
