Working notes behind pvalue_corrections — every query with its population and denominator, the scripts and their unedited output, the fold and its residue, the quotes checked against source papers, the external sources and how each was verified or rejected, the review log, and what could not be established. Corpus-level caveats that apply to every page on this site are on corpus and are not restated here.

Creating, not extending, and not overlapping. statistics:pvalue_corrections was a red link promised from start. The only neighbouring page that existed when this was written is study_preregistration, which touches multiplicity in one subsection (“For scale: the rest of the inference-hygiene stack is thin too”) and cites this page forward. That subsection's figures (15.3% of inferential, 24.5% of hypothesis-test papers) agree with this page's; this page keeps the hypothesisTest denominator throughout and adds the corrected-vs-tuple distinction the preregistration page did not need. Nothing was overwritten and no neighbouring figure was contradicted.

Reachability needed no work: start already lists P-value corrections in its outline, and study_preregistration links it twice.

The task specification quoted a figure from the old corpus. Both the numerator and the denominator moved, and one distinction the old figure did not make turned out to matter.

Two things the task's framing got right and one it did not. Right: the correction is skipped in the setting that needs it, and the page's central table quantifies that (12.9% of crawl papers vs 38.6% of user studies). Not right: inferential is the wrong denominator. A paper whose only statistics tuple is correlation or regression may have no p-value family at all, and 41.5% of the corpus never gets past descriptives. The population that needs a correction is the 1,025 papers with a hypothesis-test tuple, and the page uses that throughout. Over inferential the rate is 15.0%; over hypothesisTest it is 24.1%. Publishing 15.0% as “how often the field corrects” would have understated it by a third.

inferential, crawled and humanSubjects match OVERVIEW.md exactly (1,762 / 1,120 / 1,357), which is the check that the report's population code is the same code as the dossier's.

statistics[].method is free text and agrees run-to-run on ~0.2 of exact strings (data/extract/README.md), so it is folded before any aggregation. mcc_fold.mjs is an ordered rule list, first match wins, and a string matching no rule is returned as null and printed.

Unmapped residue: 0 distinct strings, 0 papers. All 90 distinct method strings across the 292 tuples fold.

Three orderings would silently mis-file entries if reversed, and the self-test asserts each:

node scripts/mcc_fold.mjs runs 34 cases:

34/34 fold self-tests passed

Dunn, Scheffé and Nemenyi have rules that match nothing in this corpus on their own — every corpus string naming Dunn also names Bonferroni or Holm (Dunn post-hoc tests with Holm-Bonferroni method → Holm; Dunn-Bonferroni post hoc comparison test → Bonferroni), and Scheffé and Nemenyi never appear. The rules are kept with self-test cases so they stay tested rather than rotting, and this is recorded here rather than left as an unexplained empty family.

The extraction scores a tuple as multiple-comparison-correction when the sentence is about multiple comparisons, which catches two kinds of thing that are not one. Both are excluded from every “corrected” figure on the page and both are shown in the page's own procedure table, because deleting them would be the mistake.

A query that counts kind == “multiple-comparison-correction” and stops there reports 269 where the answer is 265, and reports three papers that explicitly declined as having complied.

Eight papers describe an adjustment without naming a published procedure. They are folded to Unnamed / ad-hoc adjustment rather than guessed at, and they are listed here because the wording is the interesting part:

• multiple hypothesis correction (USENIX 2021), correcting for multiple hypothesis testing (USENIX 2023), multiple-comparison corrected (PoPETs 2024) — a correction was applied and the reader cannot tell which
• significance threshold divided by the number of groups (IEEE S&P 2024) — a described Bonferroni, deliberately not folded to Bonferroni because the string does not name it
• correction factor of two (USENIX 2024), p-value threshold adjustment for six repeated tests (IEEE S&P 2024), conservative α = 0.002 (PoPETs 2024) — a numerator and no procedure
• multiple test procedures (NDSS 2019) — feature selection, arguably a false positive of the schema, kept in the bucket rather than removed by hand

Bulk pass over every correction quote, with the –statistics filter added to quote_check.mjs for this page:

$ node scripts/quote_check.mjs --statistics multiple-comparison-correction
292 quotes checked: 167 exact, 63 partial (>=60% of 5-word windows), 62 below threshold, 0 with no full text on disk.

62 below threshold is 21% and higher than this tool usually reports. Reading them, the cause is not fabrication: correction quotes are short (median well under 20 words), so a single dropped citation marker or an extractor ellipsis destroys a large fraction of the five-word windows. “Fisher's binomial proportion test … with a Bonferroni correction.” scores 0% and is real.

Every quote used on the content page was then located by hand in data/fulltext/<year>/<venue>/<slug>/paper.cols.txt. All 18 checked out:

One thing found while checking and not put on the page. [16Kablo, Emiram; Cabarcos, Patricia Arias (2023): "Privacy in the Age of Neurotechnology: Investigating Public Attitudes towards Brain Data Collection and Use", in: Proceedings of the ACM SIGSAC Conference on Computer and Communications Security. (DOI)] writes “we adjusted the standard threshold of 0.05 to a new threshold of 0.00047 (0.005 / 106)”. 0.05/106 = 0.00047, so the printed threshold is right and the parenthetical divisor has a typo, or is a PDF-extraction artefact of “0.05”. It is a one-character slip in an otherwise exemplary paper and calling it out on the page would be a gotcha, not a lesson. Recorded here instead.

The Annals of Statistics record returns no page range; 1165–1188 in the bibliography entry is the standard citation and is not confirmed by Crossref. Every other volume, issue and page range above is as returned.

Worth recording because it is exactly the kind of thing that gets copied into a bibliography and never checked.

OpenAlex nonetheless reports doi: https://doi.org/10.2307/4615733 for the work (W2121044470, 21,859 citations), with biblio: {volume: 6, issue: null, first_page: 65, last_page: 70}. The DOI is a MAG-derived artefact: 10.2307 is JSTOR's prefix, and JSTOR did not register a DOI for this article. The bibliography entry therefore carries a url and a note saying so, not a doi.

jstor.org could not be read either: HTTP 403 to curl, and a reCAPTCHA wall to Playwright's own Chromium from this network (“JSTOR: Access Check”, block reference recorded). So the URL is confirmed to be served by JSTOR and the article page itself was not read. Volume and pages come from OpenAlex; DBLP has no record; Europe PMC does not index the journal; the Semantic Scholar API returned HTTP 429. This is the weakest-sourced entry in the bibliography and it is the most-cited paper on the page.

Error paths were exercised too: a non-numeric line raises ValueError: could not convert string to float: 'not-a-number' rather than being skipped, which is the behaviour the docstring promises.

Note that the demo output on the page was produced with SciPy 1.17.1 while the documentation quoted on the page is 1.18.0. false_discovery_control has not changed between them as far as the release notes show, but the two version numbers on the page are deliberately different and neither is a typo.

• Whether any of the 65 mixed-effects papers frames its model as a multiplicity strategy. The page says “not one frames it as an answer to multiplicity” in the body and immediately qualifies it in a footnote: none surfaced while reading correction passages, and the 65 were not read one by one. This is the softest claim on the page and it is flagged as an open question there too. Closing it is 65 paper-reads.
• Whether the other 37 power-analysis-plus-correction papers computed the correction before sizing the study. The extraction carries no ordering between two statistics tuples, so only [17Ho, Grant; Mirian, Ariana; Luo, Elisa; Tong, Khang; Lee, Euyhyun; Liu, Lin; Longhurst, Christopher A.; Dameff, Christian; Savage, Stefan; Voelker, Geoffrey M. (2025): "Understanding the Efficacy of Phishing Training in Practice", in: Proceedings of the IEEE Symposium on Security and Privacy. (DOI)], whose sentence states the sequence, can be claimed. The page says so.
• Why NDSS is lowest. 10.8% is the lowest venue rate and the page reports it without an explanation. A plausible one — NDSS publishes proportionally more systems papers whose statistics are classifier metrics rather than hypothesis tests — is not tested here. Note that classifier metrics live in detection.metric, not statistics, by design, so they are not what depresses this number.
• Whether the 33 schema-missed papers are real misses. They are listed in full in the report output. They were not read individually; the 88.2% recall figure treats all 33 as misses, which is the conservative direction — a paper mentioning Bonferroni only in related work is a sweep false positive, not a schema miss, and would raise the recall figure.
• The true correction rate. Every figure here is a rate of reporting, not of practice. A paper that corrected and did not write it down is indistinguishable from one that did not correct. statistics has no not-stated sentinel, so silence and absence are the same value.
• Whether uncorrected findings in this literature are wrong. The obvious study — take papers that ran many tests without correcting, recompute their p-values from released data, see how many claims survive — needs released p-values, which is an Artifacts problem. Listed as an open question on the page.

Q13's full list, since the page quotes only the count and one paper. Population: the 1,025 hypothesisTest papers.

37 of the 38 recruited human participants. The exception is IMC/2022/what-factors-affect-targeting-and-bids-in-online-advertising, which is also a crawl. That is the only paper in the corpus that sizes a crawl-shaped study with a correction in the calculation.

Four reviewers, all told explicitly that the author's context may not be exhaustive, and all handed the page text, the report script, its unedited output, and these notes. The three focused passes ran in parallel first; the generic pass ran after their findings were applied.

• pvalue_corrections — the page these notes back.
• corpus — the corpus-level provenance: how the 5,859 papers were selected, extracted and validated.
• study_preregistration — the sibling statistics: provenance page, and the source of this page's format.
