Struct ZScoreDetector 

pub struct ZScoreDetector { /* private fields */ }

Simple Z-score based anomaly detector

Maintains running mean and variance, flags values that exceed a threshold number of standard deviations.

Implementations

impl ZScoreDetector

pub const fn new(threshold_k: f64) -> Self

Create a new Z-score detector

pub fn observe(&mut self, value: f64)

Observe a new value (updates running statistics)

pub fn variance(&self) -> f64

Get the variance

pub fn std_dev(&self) -> f64

Get the standard deviation

pub fn is_anomaly(&self, value: f64) -> bool

Check if a value is an anomaly

pub fn z_score(&self, value: f64) -> f64

Get the Z-score for a value

pub const fn mean(&self) -> f64

Get current mean

pub const fn count(&self) -> u64

Get count

pub const fn reset(&mut self)

Reset the detector
