Struct meansd::binned::Width

pub struct Width { /* private fields */ }

An online algorithm for calculating mean and standard deviation with binning and a fixed bin width.

Resources

The memory requirement is effectively constant, growing only ever so slightly with each new bin.

Implementations

impl Width

pub fn new(width: NonZeroU32) -> Self

Returns a new and empty data structure with width bin width.

pub const fn width(&self) -> NonZeroU32

Returns the bin width.

Trait Implementations

impl Binned for Width

fn update(&mut self, x: f64)

Updates the data structure with a new observation x.

fn bins(&self) -> Box<dyn Iterator<Item = Bin> + '_>

Returns an iterator over all bins.

fn data(&self) -> Box<dyn Iterator<Item = (Bin, &MeanSD)> + '_>

Returns an iterator over the non-empty bins.

fn all(&self) -> &MeanSD

Returns a reference to the stats for all observations.

impl Clone for Width

fn clone(&self) -> Width

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Width

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

Formats the value using the given formatter.
