Crate ndarray_stats 

The ndarray-stats crate exposes statistical routines for ArrayRef, the n-dimensional array data structure provided by ndarray.

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.);
• measures of deviation (count equal, L1, L2 distances, mean squared err etc.)
• histogram computation.

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

Our work is inspired by other existing statistical packages such as NumPy (Python) and StatsBase.jl (Julia) - any contribution bringing us closer to feature parity is more than welcome!
