Struct P2Quantile 

pub struct P2Quantile { /* private fields */ }

Constant-memory P² estimator for one interior quantile.

Implementations

impl P2Quantile

pub fn new(quantile: f64) -> Result<Self, RillError>

Create an estimator for quantile in the open interval (0, 1).

pub const fn quantile(&self) -> f64

Requested quantile.

pub fn value(&self) -> Option<f64>

Estimated quantile, or None before the first observation.

The first four samples use exact linear interpolation over the retained bootstrap values. From the fifth sample onward this returns the central P² marker.

pub fn reset(&mut self)

Reset to the empty state while retaining the requested quantile.
