{"slug":"yuan1z0825-nature-statistics","name":"nature-statistics","description":">-","long_description":"---\nname: nature-statistics\ndescription: >-\n  Audit, revise, or draft manuscript statistical reporting for Nature / high-impact journal submissions. Use when the user asks to check statistical analysis sections, p values, confidence intervals, sample size, biological versus technical replicates, randomization, blinding, multiple-comparison correction, model assumptions, figure legends, Results statistics wording, reviewer comments about statistics, or Chinese academic drafts needing publication-ready Statistical analysis text. Also trigger on general paper-statistics requests such as 统计审查、统计分析小节、统计方法、p值、样本量、重复数、多重比较、置信区间、效应量、图注统计、审稿人统计意见.\n---\n\n# Nature Statistics Reporting Skill\n\nUse this skill to make manuscript statistics transparent, reproducible, and appropriately bounded. It is a reporting and review skill, not a substitute for a statistician reanalysing raw data unless the user supplies the data and explicitly asks for computation.\n\n## Default stance\n\n- Prioritize design transparency over decorative statistical language.\n- Separate three questions: what was measured, what unit was analysed, and what inference was claimed.\n- Treat the independent experimental unit as the default `n`; do not silently treat cells, fields of view, repeated readings, spectra, model runs, or technical replicates as independent biological or experimental samples.\n- Prefer effect sizes, uncertainty intervals, sample sizes, and exact test definitions over significance-only phrasing.\n- State missing information as `AUTHOR_INPUT_NEEDED` instead of inventing sample sizes, tests, software, corrections, exclusion rules, randomization, or blinding.\n- If a journal-specific instruction, study-type guideline, or field standard conflicts with this skill, follow the more specific source and mark the source used.\n\n## Accepted inputs\n\nThe skill may receive:\n\n- a Statistical analysis / Methods subsection\n- Results paragraphs containing test statistics or p values\n- figure panels, legends, captions, or source-data notes\n- reviewer comments about statistics\n- author notes in Chinese or English\n- tables of reported comparisons\n- raw or summary data, only when the user wants a concrete reanalysis or figure-statistics check\n\nIf the input is partial, run a bounded audit and state which parts cannot be assessed.\n\n## Workflow\n\n1. **Classify the task.** Decide whether the user wants audit, rewrite, draft, reviewer-response support, figure-statistics alignment, or data-backed reanalysis.\n2. **Extract the design.** Identify groups, treatments, time points, endpoints, blocking factors, repeated measures, randomization, blinding, exclusions, and missing-data handling.\n3. **Define `n` and replication.** Separate independent experimental units, biological replicates, technical replicates, repeated measures, cells/fields/subsamples, simulations, and pooled observations.\n4. **Map claims to analyses.** For each result claim, record the comparison/model, test family, assumptions, correction strategy, effect estimate, uncertainty, and exact p-value policy.\n5. **Check common failure modes.** Use `references/common-failure-modes.md` when the text involves nested data, many comparisons, cell-level measurements, interaction claims, correlations, regression, outliers, small samples, or significance-only reasoning.\n6. **Check reporting completeness.** Use `references/statistical-reporting.md` to verify that Methods and Results give enough information for readers and reviewers to understand the analysis.\n   If the target is the flagship journal Nature, also use\n   `references/nature-article-requirements.md` for its exact tail, `n`, repeat,\n   P-value, test-statistic and degrees-of-freedom requirements.\n   If the target is Nature Machine Intelligence, also use\n   `../nature-shared/journal-formats/nature-machine-intelligence.md` for its\n   legend-statistics, source-data, reporting-summary and stage-specific checks.\n7. **Align figure statistics.** Use `references/figure-statistics.md` when figure legends, panel labels, stars, error bars, box plots, violin plots, source data, or supplementary figure notes are involved.\n8. **Draft or revise.** Produce conservative, ready-to-paste text. Keep claims within the supplied design and evidence. Do not upgrade statistical association into mechanism or causality.\n9. **Run final QA.** Use `references/reviewer-checklist.md` before final delivery for severity labels, unresolved author questions, and reviewer-facing risk.\n\n## Output format\n\nUnless the user asks for another format, return:\n\n```text\nStatistics review scope\n- Input reviewed:\n- Boundary / missing materials:\n- Study design readout:\n- Independent unit and replication readout:\n\nMajor statistical issues\n- [P0/P1/P2] Issue:\n  Evidence from supplied text:\n  Why it matters:\n  Fix:\n\nReady-to-paste revision\n[Rewritten Statistical analysis / Results / figure legend text]\n\nAUTHOR_INPUT_NEEDED\n- [short factual questions only]\n\nReviewer-risk note\n- What a statistical reviewer may still challenge:\n```\n\nFor a clean drafting request with enough information, skip the long issue list and return:\n\n```text\nDraft Statistical analysis\n[ready-to-paste text]\n\nReporting notes\n- n definition:\n- tests/models:\n- multiple comparisons:\n- software/version:\n- unresolved fields:\n```\n\n## Red lines\n\n- Do not invent p values, sample sizes, degrees of freedom, confidence intervals, software versions, correction methods, preregistration, exclusion rules, or power calculations.\n- Do not recommend a statistical test as final when the unit of analysis or design is unclear.\n- Do not accept `n = number of cells/images/measurements` as independent replication without checking the experimental hierarchy.\n- Do not use “significant” as a synonym for important, large, causal, or biologically meaningful.\n- Do not hide non-significant or weak results by rewriting them into stronger claims.\n- Do not give medical, regulatory, or clinical-trial statistical advice beyond reporting checks unless the user provides the relevant protocol and asks for bounded manuscript wording.\n\n## Related files\n\n| File | Open when |\n|---|---|\n| [references/source-basis.md](references/source-basis.md) | You need the source hierarchy or want to justify why the skill emphasizes transparency, reproducibility, and design reporting |\n| [references/nature-article-requirements.md](references/nature-article-requirements.md) | The target is the flagship journal Nature or the user requests its exact statistical submission checklist |\n| [../nature-shared/journal-formats/nature-machine-intelligence.md](../nature-shared/journal-formats/nature-machine-intelligence.md) | The target is Nature Machine Intelligence or NMI-specific legend, source-data, reporting or stage requirements affect the audit |\n| [references/statistical-reporting.md](references/statistical-reporting.md) | You are drafting or auditing Statistical analysis, Methods, Results, or Supplementary Methods text |\n| [references/common-failure-modes.md](references/common-failure-modes.md) | You see nested measurements, many comparisons, interaction claims, correlation/regression, outliers, tiny samples, or overstrong p-value language |\n| [references/figure-statistics.md](references/figure-statistics.md) | You are checking figure legends, panel statistics, error bars, stars, box/violin plots, source-data notes, or graphical reporting |\n| [references/reviewer-checklist.md](references/reviewer-checklist.md) | You are finalizing an audit or preparing a reviewer-facing risk summary |\n| [../nature-shared/core/consistency-sweep.md](../nature-shared/core/consistency-sweep.md) | The same statistic appears in more than one place, or interval terminology is in question: one metric at two precisions across table and text, SD/Std abbreviation drift, `confidence interval` used where `prediction interval` is meant, or overlapping error bars described as outperformance |\n\n## Source hierarchy\n\nUse sources in this order:\n\n1. User-supplied manuscript, data, protocol, statistical analysis plan, reviewer comments, and journal instructions.\n2. Nature Portfolio reporting standards and reporting-summary requirements.\n3. Nature Methods / Nature Portfolio statistics guidance summarized in `references/source-basis.md`.\n4. Study-type reporting guidelines where relevant, for example CONSORT, STROBE, PRISMA, ARRIVE, or field-specific community standards.\n5. Conservative statistical reporting practice.\n\nIf the supplied material is insufficient for a defensible statistical recommendation, ask for the missing design facts or provide a bounded wording option rather than guessing.\n","tagline":">-","category":"automation","tags":["agent-skill"],"author":"Yuan1z0825","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"Yuan1z0825/nature-skills","creatorName":"Yuan1z0825","creatorUrl":"https://github.com/Yuan1z0825","sourceUrl":"https://github.com/Yuan1z0825/nature-skills/tree/main/skills/nature-statistics","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/yuan1z0825-nature-statistics#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
