ndarray-stats

This crate provides statistical methods for ndarray's ArrayBase type.

Currently available routines include:

order statistics (minimum, maximum, median, quantiles, etc.);
summary statistics (mean, skewness, kurtosis, central moments, etc.)
partitioning;
correlation analysis (covariance, pearson correlation);
measures from information theory (entropy, KL divergence, etc.);
deviation functions (distances, counts, errors, etc.);
histogram computation.

See the documentation for more information.

Please feel free to contribute new functionality! A roadmap can be found here.

0.6.0
- Breaking changes
  - Minimum supported Rust version: 1.64.0
  - Updated to ndarray:v0.16.0
  - Updated to approx:v0.5.0
- Updated to ndarray-rand:v0.15.0

0.5.1
- Fixed bug in implementation of MaybeNaN::remove_nan_mut for f32 and f64 for views with non-standard layouts. Before this fix, the bug could cause incorrect results, buffer overflows, etc., in this method and others which use it. Thanks to @JacekCzupyt for reporting the issue (#89).
- Minor docs improvements.
