Struct Summary 

pub struct Summary<T> {
    pub n: usize,
    pub min: T,
    pub max: T,
    pub mean: f64,
    pub variance: f64,
}

Statistical summary for a given iterator of numbers.

Calculates all the information using single pass over the data. Mean and variance are calculated using streaming algorithm described in Art of Computer Programming, Vol 2, page 232.

Fields

n: usize

min: T

max: T

mean: f64

variance: f64

Implementations
