Changelog¶

0.7.0 - 2026-05-16¶

Added¶

• Alternative, Frame, and ToRNG type aliases for function parameters.

Changed¶

• frame='hull' sampling for improved performance, changing seeded results.

0.6.1 - 2026-05-13¶

Fixed¶

• ValueError when a NumPy array was passed as frame.

0.6.0 - 2026-05-07¶

Added¶

• 'hull' option to the frame parameter for sampling from the convex hull.

Removed¶

• typing_extensions dependency for Python 3.11.

0.5.0 - 2026-03-27¶

Added¶

• frame parameter to hopkins() and hopkins_test() for specifying a custom rectangular sampling frame.

0.4.0 - 2026-02-16¶

Fixed¶

• ModuleNotFoundError on Python 3.12 when typing_extensions was not installed.

Removed¶

• HopkinsUndefinedWarning and the explicit check for degenerate data; degenerate cases now rely on NumPy to warn and still produce NaN.

0.3.1 - 2026-01-27¶

Fixed¶

• hopkins() and hopkins_test() to not modify input data in-place when called with toroidal=True.

0.3.0 - 2026-01-19¶

Added¶

• toroidal option to hopkins() and hopkins_test() to compute the statistic with toroidal topology (i.e., periodic boundary conditions).

0.2.0 - 2026-01-02¶

Added¶

• hopkins_test() to perform a Hopkins test by computing the statistic and the \(p\)-value under the \(\mathrm{Beta}(m, m)\) null distribution.

Fixed¶

• rng parameter typing to use RNGLike and SeedLike aliases following SPEC 7, broadening the range of accepted seed and generator types.

0.1.0 - 2025-12-28¶

Added¶

• hopkins() to compute the Hopkins statistic for \(d\)-dimensional data following Cross & Jain (1982), using a (hyper-)rectangular sampling frame.
