tidy_summary: linear quantile interpolation (queued for 0.1.1)#21
Merged
Conversation
polars `.quantile()` defaults to "nearest", which diverges from R's quantile() (type 7), NumPy, and the quartiles drawn by Plotly/ggplot2 boxplots. Add an `interpolation="linear"` parameter (new default) so tidy_summary's five-number summary matches the standard textbook/R convention and the boxplots shown beside it. Pass interpolation="nearest" to restore the old behavior. Queued for the next release (0.1.1) — not yet published. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

R's chisq.test and this package's prop_test both default to Yates' continuity correction; chisq_test previously hardcoded correction=False, an inconsistency. Add a `correct: bool = True` parameter (applied only to 2x2 tables, like R and scipy); pass correct=False for the uncorrected Pearson statistic that matches the simulation-based calculate(stat="Chisq"). 322 tests pass at 100% coverage. Queued for 0.1.1 — not yet released. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…aults) Both additions previously flipped a default, changing results for existing 0.1.0 users. Revert the defaults to 0.1.0 behavior and keep the new behavior opt-in: - tidy_summary(interpolation=): default back to "nearest"; pass "linear" for R's quantile() type 7 / Plotly/ggplot2 boxplot quartiles. - chisq_test(correct=): default back to False (uncorrected Pearson, matching calculate(stat="Chisq")); pass correct=True for R's chisq.test/prop_test. Both are now purely additive (new opt-in parameters) and safe for a 0.1.1 patch. Also document a CHANGELOG/RELEASING convention requiring any breaking change to get a dedicated "⚠️ Breaking changes" section and a non-patch version bump. 322 tests, 100% coverage, ruff clean.

Adds an
interpolation="linear"parameter totidy_summary(new default).Why: polars
.quantile()defaults to"nearest", which diverges from R'squantile()(type 7), NumPy, and the quartiles drawn by Plotly/ggplot2 boxplots. With"linear",tidy_summary's Q1/Q3 match the standard textbook/R convention and the boxplots shown beside them in the book. Passinterpolation="nearest"to restore prior behavior.Full test suite passes at 100% coverage (322 tests).
Do not release yet — holding off since 0.1.0 was just published. Queue for 0.1.1.
