Implementations

impl ZScoreNormF64Builder

pub fn alpha(self, alpha: f64) -> ZScoreNormF64Builder

Direct smoothing factor. Must be in (0, 1) exclusive.

pub fn min_samples(self, min: u64) -> ZScoreNormF64Builder

Minimum samples before values are valid. Default: 2.

pub fn seed(self, mean: f64, variance: f64) -> ZScoreNormF64Builder

Pre-loads mean and variance from calibration data.

pub fn build(self) -> Result<ZScoreNormF64, ConfigError>

Builds the z-score normalizer.

Errors
