ProbabilityMoment

eqiora::kernel

Enum ProbabilityMoment 

pub enum ProbabilityMoment {
    Expectation,
    Variance,
    Covariance,
}
Description

A moment under an exact declared probability law, not a finite-sample estimate.

Variants§

§

Expectation

Integral of a random quantity against the normalized law.

§

Variance

Centered second moment of one real scalar random quantity.

§

Covariance

Centered paired moment of two real scalar random quantities under the same law.

Implementations§

§

impl ProbabilityMoment

Signature links:§ProbabilityMoment

pub fn validate_weights( weights: impl IntoIterator<Item = f64>, ) -> Result<(), Diagnostic>

Signature links:validate_weightsIntoIteratorf64Result()Diagnostic

Admit proportional weights with finite nonnegative entries and positive total mass. This checks normalization, not probability-law or sample provenance. It does not sum in floating point, so a finite ratio need not have a representable sum.

§Errors

Rejects empty/all-zero weights, negative values, NaN and infinity.

pub fn evaluate( self, rows: &[Vec<ValueLiteral>], weights: &[f64], ) -> Result<ValueLiteral, Diagnostic>

Signature links:evaluateVecValueLiteralf64ResultValueLiteralDiagnostic

Evaluate a finite weighted moment, normalizing the nonnegative weights explicitly.

Each row contains this moment’s ordered quantities. This arithmetic operation alone does not establish that rows exhaust a distribution, form an ensemble, are independent, or yield an unbiased estimator. Those claims require the caller’s admitted law or sample-design context.

Binary64 inputs are accumulated exactly within the shared rational work bound and rounded once on output. Overflow or exhausted arithmetic work rejects; no cancellation tolerance, clipping, or order-dependent floating sum is used.

§

impl ProbabilityMoment

Signature links:§ProbabilityMoment

pub const fn arity(self) -> usize

Signature links:arityusize

Number of ordered random-variable expressions consumed by this moment.

pub fn output_type(self, values: &[&ValueType]) -> Result<ValueType, Diagnostic>

Signature links:output_typeValueTypeResultValueTypeDiagnostic

Derive the moment’s units from its integrands, independently of evaluated values.

The initial moment profile admits real invariant scalar quantities. Complex covariance conventions, tensor contractions and sampled estimators are separate meanings and cannot be inferred from component storage.
