Struct RunningStats 

pub struct RunningStats<S: Scalar> { /* private fields */ }

Running statistics using Welford’s online algorithm.

Memory-efficient for streaming data or very large ensembles.

Implementations

impl<S: Scalar> RunningStats<S>

pub fn new() -> Self

Create a new running statistics accumulator.

pub fn update(&mut self, value: S)

Update statistics with a new value (Welford’s algorithm).

pub fn count(&self) -> usize

Number of samples seen.

pub fn mean(&self) -> S

Current mean estimate.

pub fn variance(&self) -> S

Current variance estimate (sample variance with Bessel correction).

pub fn std(&self) -> S

Current standard deviation estimate.

pub fn standard_error(&self) -> S

Standard error of the mean.

pub fn min(&self) -> S

Minimum value seen.

pub fn max(&self) -> S

Maximum value seen.

pub fn merge(&mut self, other: &RunningStats<S>)

Merge another RunningStats into this one (parallel reduction).

Trait Implementations

impl<S: Clone + Scalar> Clone for RunningStats<S>

fn clone(&self) -> RunningStats<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + Scalar> Debug for RunningStats<S>

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

Formats the value using the given formatter.

impl<S: Scalar> Default for RunningStats<S>

fn default() -> Self

Returns the “default value” for a type.
