Function rgsl::statistics::covariance [−] [src]

pub fn covariance(data1: &[f64], stride1: usize, data2: &[f64], stride2: usize, n: usize) -> f64

This function computes the covariance of the datasets data1 and data2 which must both be of the same length n.

covar = (1/(n - 1)) \sum_{i = 1}^{n} (x_i - \Hat x) (y_i - \Hat y)

Search Tricks

Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g. vec -> usize or * -> vec)
