Struct CorrelationMatrix 

pub struct CorrelationMatrix { /* private fields */ }

Pairwise Pearson correlation matrix for a set of variables.

Implementations

impl CorrelationMatrix

pub fn from_rows(rows: &[&[f64]]) -> Result<Self>

Build a correlation matrix from rows of observations.

Each inner slice is one variable’s observations (all must have the same length and at least 2 elements).

pub fn from_rows_labeled(rows: &[&[f64]], labels: &[&str]) -> Result<Self>

Build a labeled correlation matrix.

pub fn get(&self, i: usize, j: usize) -> f64

Get the correlation between variable i and variable j.

pub fn n(&self) -> usize

Number of variables.

pub fn labels(&self) -> Option<&[String]>

Variable labels, if provided.
