This crate provides statistical methods forndarray'sArrayBase 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 thedocumentation for more information.

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

  • Fixed bug in implementation ofMaybeNaN::remove_nan_mut forf32 andf64 for views with non-standard layouts. Before this fix, the bug couldcause incorrect results, buffer overflows, etc., in this method and otherswhich use it. Thanks to@JacekCzupyt forreporting the issue (#89).
