What it does

Cps Data Analysis is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when running and reporting the analyses for a Comparative Political Studies (CPS) manuscript — estimation, uncertainty, robustness, and multi-method triangulation on comparative data. Sets analysis norms; it does not choose the identification strategy (see cps-research-design).

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Data analysis. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cps Data Analysis loads about 1.7k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 707 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when running and reporting the analyses for a Comparative Political Studies (CPS) manuscript — estimation, uncertainty, robustness, and multi-method triangulation on comparative data. Sets analysis norms; it does not choose the identification strategy (see cps-research-design).

Data Analysis (cps-data-analysis)

Once the design is fixed (cps-research-design), this skill governs how the analyses are run and reported so a CPS reviewer trusts them. Comparative data bring distinctive hazards: few clusters (countries), cross-national measurement error, missing data that differ by regime, and the temptation to over-read a panel correlation as causal. The standard is modern, transparent, and replication-ready.

When to trigger

  • Estimating the main results, robustness, and heterogeneity
  • A reviewer questioned standard errors, specification, measurement, or fragility of the result
  • Deciding what goes in the main text vs. the supplementary/online appendix
  • Triangulating quantitative estimates with case evidence

Analysis priorities (in order)

  1. Main estimate that matches the design. The headline specification should be the one the identification argument justifies — not the one with the biggest coefficient or most stars.
  2. Honest uncertainty. Cluster at the assignment level (usually country / country-year); with few countries use wild-cluster bootstrap or randomization inference. Report CIs, not just stars.
  3. Measurement transparency. Name the source and coding of each comparative variable (e.g., V-Dem, Polity, CSES, Manifesto Project); show robustness to alternative codings of the key construct.
  4. Robustness as a coherent story. Alternative specifications, samples, codings, and estimators that probe the threats named in the design — not a scattershot table of every variant.
  5. Heterogeneity by theory. Subgroups/scope conditions pre-specified by the mechanism (cps-theory-building), not data-mined; adjust for multiple comparisons.
  6. Mechanism evidence. Tie the quantitative result to the mechanism — mediation cautiously, or case evidence in a multi-method design.

Cross-national measurement errorresults flip across codingsshow robustness to V-Dem/Polity/alt scales
Differential missingnesssample changes by regime typereport attrition; multiple imputation with caution
Time-series confoundingspurious trend correlationsunit + period FE; over-time placebo

Failure-mode audit

Run this audit before interpreting the main coefficient:

  • Concept equivalence: Does the key variable mean the same thing across regimes, languages, regions, or institutions? If not, report measurement-invariance checks, alternative codings, or scope limits.
  • Selection into observation: Are only more democratic, richer, more peaceful, or better-measured cases observed? Report the observation process and show how estimates change under credible sample restrictions.
  • Temporal dependence: Are observations mechanically persistent across years? Use lag structure, unit trends, event-time plots, or placebo leads to avoid re-labeling persistence as effect.
  • Cluster leverage: Does one country, region, election, conflict, or reform episode drive the result? Show leave-one-cluster-out or influence diagnostics for claims that hinge on few cases.
  • Subgroup multiplicity: If theory predicts heterogeneity, pre-specify the dimensions and report how many comparisons were examined.

The output should connect each failure mode to a design threat. Do not add a robustness table unless it answers a named threat in cps-research-design.

Execution bridge (StatsPAI / Stata MCP)

Run the battery, don't just enumerate it. Full map: execution-with-mcp. CPS is comparative politics — cross-national and sub-national designs; emphasize identification and clustered / multiway inference.

  • Many outcomes / specifications: romano_wolf (step-down FWER) or benjamini_hochberg — report the adjusted threshold.
  • OVB sensitivity: oster_delta / sensemakr.
  • Inference: wild_cluster_bootstrap (few clusters), twoway_cluster / conley; multilevel data → cluster at the right level.
  • Re-fit off one handle: audit_result(result_id) lists the missing checks and the exact suggest_function for each.
  • Exhibits: etable / did_summary_to_latex from the handle — no retyped numbers.

Keep the decisive checks in the body and the exhaustive battery in the supplement. See the executed chain in the JF execution walkthrough.

Checklist

  • Headline specification = the one the design justifies
  • SEs clustered at the assignment level; few-cluster correction where needed
  • Every comparative variable's source and coding named; key construct robust to alt codings
  • Robustness probes the design's named threats; not a kitchen sink
  • Heterogeneity pre-specified by theory; multiple testing addressed
  • Main text vs. appendix split is deliberate; every appendix result is referenced
  • All results reproduce from the script destined for the CPS Dataverse

Anti-patterns

  • Treating a cross-national panel correlation as causal without the design to back it
  • Default OLS SEs with 20 countries (massively over-rejects)
  • Cherry-picking the coding of the key variable that gives significance
  • Robustness theater — many variants that never test the actual threat
  • Data-mined subgroups reported as confirmed heterogeneity
  • Results in the paper that the deposited code does not reproduce

Output format

【Headline result】estimate + CI, with the design it rests on
【Inference】clustering level + few-cluster correction if any
【Measurement】sources/codings + alt-coding robustness
【Failure-mode audit】concept equivalence / observation selection / temporal dependence / cluster leverage / multiplicity
【Robustness】the design-threats probed
【Heterogeneity】theory-driven subgroups + multiple-testing fix
【Reproducible?】script regenerates every exhibit [Y/N]
