[dependabot]

Bumps statrs from 0.18.0 to 0.19.0.

Release notes

Sourced from statrs's releases.

v0.19.0

Added

• Add initial no_std support
• gate density estimation behind a "kde" feature
• add first implementation of kernel density estimation.
• add bandwith support for knn density estimation.
• add a more generic implementation of knn density estimation.
• add knn density estimation with kdtree rs tree.
• add OnlineMoments accumulator using Welford
• Add WebAssembly RNG support and update nalgebra
• (distribution) narrow error type to avoid trait object
• (distribution) add non-panicking try_inverse_cdf
• autofix.ci for lint and fmt
• (geometric) finer panic bounds
• (function) add comprehensive kernel suite for KDE and smoothing (#193)
• update to 2024 edition, apply formatting and fix new clippy lints
• [breaking] rely on prec module for precision needs and consts for math constants
• use crate::prec macro assertions in tests instead of approx directly
• (prec) write macros that delegate to approx using our defaults
• add std feature
• rename cov_chol_decomp to clone_cov_chol_decomp and return a cloned matrix
• add methods for covariance decomposition, mean, covariance, and precision in MultivariateNormal
• add accessor methods to various distribution
• (stats_tests) implement KS test
• enhance Levy distribution with comprehensive documentation and methods
• add Levy distribution
• (stats_tests) implement chisquare
• (stats_tests) implement skewtest
• (stats_tests) implement mannwhitneyu
• (stats_tests) implement ttest_onesample
• (stats_tests) implement f_oneway

Fixed

• format assertion message with precision
• fail autofix when clippy --fix can't clear every lint
• drop PAT from autofix-ci.yml
• make autofix clippy match other parts of ci
• Automate MSRV lockfile updates
• update to rand 0.10 and use seeded rng for tests
• fix imports and add some tests.
• kernel density computation.
• drop excess precision requirements
• wrap online stats with iter_statistics for #376
• Refresh MSRV lockfile
• Leave getrandom backend selection to applications
• Use valid order statistics benchmark inputs
• correct entropy formulas for Pareto, Geometric, StudentsT, and Dirichlet
• safeguard Gamma::inverse_cdf Newton step for shape < 1

... (truncated)
