Struct ScoreWithConfidence 

pub struct ScoreWithConfidence {
    pub score: AnomalyScore,
    pub trees_evaluated: usize,
    pub stddev: f64,
    pub stderr: f64,
}

Scored point plus the per-tree sample statistics behind it.

Serialisable under the serde feature so SIEM / audit sinks can emit the full confidence context alongside the raw score.

Fields

score: AnomalyScore

Mean anomaly score — identical to crate::RandomCutForest::score’s output.

trees_evaluated: usize

Number of trees that contributed (= ensemble size minus any empty trees).

stddev: f64

Unbiased sample standard deviation across per-tree scores. 0.0 when only one tree contributed.

stderr: f64

Standard error of the mean: stddev / sqrt(n). The width of the z = 1.96 confidence interval is 2 · z · stderr.

Implementations

impl ScoreWithConfidence

pub fn ci(&self, z: f64) -> (f64, f64)

Symmetric confidence interval (lower, upper) at factor z. The interval is clamped at zero on the lower side — anomaly scores are non-negative by construction.

pub fn ci95(&self) -> (f64, f64)

95 % CI — convenience wrapper around Self::ci with DEFAULT_Z_FACTOR.

pub fn relative_stderr(&self) -> f64

Relative stderr — stderr / max(|mean|, ε). Mirrors the metric used by crate::RandomCutForest::score_early_term so callers can compare the two paths.

Trait Implementations

impl Clone for ScoreWithConfidence

fn clone(&self) -> ScoreWithConfidence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScoreWithConfidence

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScoreWithConfidence

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScoreWithConfidence

fn eq(&self, other: &ScoreWithConfidence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ScoreWithConfidence

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
