Struct quantiles::greenwald_khanna::Stream

pub struct Stream<T> where
    T: Ord,  { /* fields omitted */ }

The summary S of the observations seen so far.

Methods

impl<T> Stream<T> where
    T: Ord, 

fn new(epsilon: f64) -> Stream<T>

Creates a new instance of a Stream

fn insert(&mut self, v: T)

Locates the correct position in the summary data set for the observation v, and inserts a new tuple (v,1,floor(2en)) If v is the new minimum or maximum, then instead insert tuple (v,1,0).

fn quantile(&self, phi: f64) -> &T

Compute the epsilon-approximate phi-quantile from the summary data structure.

fn p(&self) -> usize

Calculate p = 2epsilon * n

fn n(&self) -> usize

The number of observations inserted into the stream.

fn s(&self) -> usize

Indication of the space usage of the summary data structure Returns the number of tuples in the summary data structure.

Trait Implementations

impl<T: Debug> Debug for Stream<T> where
    T: Ord, 

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
