docs: propagate recent fixes across stats/base/dists/* packages

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-07-04 21:17 UTC and 2026-07-05 12:00 UTC to sibling packages that carry the same defects.

docs: fix logEachMap format specifier (source: 4e24379)

The logEachMap format string uses stdlib's format spec, not C printf. %lf is not a valid token; %0.4f is the intended form. 4e24379 fixed the tukey-lambda/mode example; the same wrong specifier is present in the following sibling distribution READMEs and their examples/index.js:

• stats/base/dists/anglit/mean
• stats/base/dists/anglit/median
• stats/base/dists/anglit/quantile
• stats/base/dists/halfnormal/mean

Replacement is confined to the logEachMap line in each file; the %lf tokens inside C printf examples elsewhere in each README are untouched.

chore: fix copy-pasted equation labels (source: 6e257ba)

6e257ba corrected a betaprime/mode/README.md whose equation label, data-equation, and image path still read _expectation from a mean-package copy-paste. The same three tokens plus a stale alt attribute appear in:

• stats/base/dists/levy/mode — label, data-equation, and SVG path corrected to _mode.
• stats/base/dists/levy/median — same three tokens corrected to _median, plus alt="Mode for a Lévy distribution." → "Median for a Lévy distribution." on both the <equation> and the <img> element.

docs: add missing @private tag (sources: a1a8d32, 7d1419f)

Both source commits inserted * @private into the JSDoc block of stats/base/dists/log-logistic/{cdf,quantile}/lib/native.js because the wrapper is an internal binding, not part of the public API. The same JSDoc block in the following native.js files omits the tag:

• stats/base/dists/bradford/entropy
• stats/base/dists/cosine/quantile
• stats/base/dists/gamma/pdf
• stats/base/dists/logistic/cdf
• stats/base/dists/poisson/pmf
• stats/base/dists/signrank/pdf

Insertion form matches the source commits exactly: one new * @private line between the blank comment line following the description and the first @param.

Validation

• Pattern signatures were derived from the source commits' diffs and searched under lib/node_modules/@stdlib/stats/base/dists/.
• Two independent validation passes read each candidate file in full, confirmed the defect was present, and verified the proposed patch is self-contained. Style consistency matches the source commits verbatim.
• Deliberately excluded: %lf occurrences inside C printf examples (legitimate C format specifiers); README label="eq:*_expectation" occurrences in mean/ packages (label is semantically correct there); autogenerated files (math/base/special/*/lib/rational_pq.js — matched return Infinity but carry a "generated file" marker, so the fix belongs in the generator).
• Grouping: one commit per source fix pattern to keep the audit trail per-pattern.

Disclosure

This PR was authored by Claude Code as part of an automated fix-propagation routine that scans the previous 24 hours of commits merged to develop, extracts generalizable fix patterns, locates sibling packages with the same defect, and produces a draft PR for maintainer review. Each candidate site was independently validated by two adversarial review passes before the patch was applied.
