Struct Statistics 

pub struct Statistics<T> {
    pub mean: T,
    pub variance: T,
    pub sigma: T,
    pub max: T,
    pub min: T,
    pub range: T,
    /* private fields */
}

Running statistics of a data stream, updated by add. Sums are accumulated relative to offset (a value close to the data) to reduce cancellation in the variance.

Fields

mean: T

Mean.

variance: T

Population variance (divided by the number of samples).

sigma: T

Standard deviation, sqrt(variance).

max: T

Largest value.

min: T

Smallest value.

range: T

max - min.

Implementations

impl<T> Statistics<T>

where T: Float + AddAssign,

pub fn new(offset: T) -> Self

Empty statistics. offset should be close to the data (e.g. the first sample); it only affects round-off.

pub fn add(&mut self, data: T)

Add a sample and update all statistics.

Trait Implementations

impl<T: Clone> Clone for Statistics<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Copy> Copy for Statistics<T>

impl<T: Debug> Debug for Statistics<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
