Description

What is the purpose of this pull request?

This pull request normalizes three metadata/documentation inconsistencies in @stdlib/stats/base/dists/frechet where individual packages had drifted from the pattern shared by the rest of the namespace. No observable behavior, signatures, or test expectations change.

Namespace summary. stats/base/dists/frechet has 14 members (cdf, ctor, entropy, kurtosis, logcdf, logpdf, mean, median, mode, pdf, quantile, skewness, stdev, variance). Structural features (file tree, package.json/manifest.json shape, README section skeleton, test/benchmark/example naming) and semantic features (public signatures, return kind, validation prologue, error construction, JSDoc shape, dependencies) were extracted per package and compared at a 75% majority threshold (⌈14 × 0.75⌉ = 11). Features with a clear majority include the C-backed file layout, package.json structure, the distribution-level keywords cluster, and JSDoc shape within each of the two sub-templates. Features without a clear majority — the value-function vs. property-function split (factory.js, extra fixtures), @returns types, per-function dependencies, and per-function example counts — were excluded from drift analysis as semantically justified.

Three outliers cleared structural, semantic, and cross-reference validation:

pdf

pdf/package.json carried only frechet from the distribution-level keyword cluster, dropping weibull, inverse, extreme, and value. Fréchet is the inverse Weibull / Type-II extreme value distribution, so these are distribution-level descriptors, not function-specific ones: weibull/inverse/extreme appear in 13/14 members and value in 12/14. Restored the canonical frechet, weibull, inverse, extreme, value run.

quantile

quantile/package.json already carried weibull, inverse, and extreme but omitted value, splitting the "extreme value" descriptor that the sibling majority keeps intact (12/14). Added value after extreme.

logpdf

The outer JSDoc description in logpdf/lib/factory.js read "logarithm of the probability density function (PDF)", dropping "natural". The package's own lib/main.js and the file's inner private-function JSDoc both say "natural logarithm", the implementation uses ln, and 4/5 value-function siblings carry "natural" in their factory descriptions. Restored "natural" to match.

Any other information relevant to this pull request?

Corrections are grouped one commit per package for a per-package audit trail. Validation: each candidate passed a three-part review — a semantic review (intentional deviation vs. unintentional drift), a cross-reference review (no test, example, benchmark, or doctest pins the changed strings; keywords is never imported and the JSDoc text appears only in source/type/header files), and a structural review confirming the majority pattern is the one that should apply. Deliberately excluded: ctor (a pure-JS distribution class that legitimately lacks C infrastructure, manifest.json, and the ## C APIs section — a different package kind, not drift); the value-function/property-function sub-template differences; and mean/README.md, whose linked, qualified prose ([expected value][mean], α > 0) is used consistently throughout that README and is a stylistic choice rather than a mechanical one-line deviation.

This PR was prepared with Claude Code: it extracted structural and semantic features across the frechet namespace, identified the majority pattern per feature, flagged the three deviating packages, and drafted the metadata/documentation corrections. Each correction was validated against the sibling majority and checked to ensure no tests or examples depend on the changed strings. A human should review before merge.
