Struct AssociationRule 

pub struct AssociationRule {
    pub antecedent: Vec<String>,
    pub consequent: Vec<String>,
    pub support: usize,
    pub support_pct: f64,
    pub confidence: f64,
    pub lift: f64,
    pub classification: String,
}

An association rule antecedent → consequent with support, confidence, and lift.

Fields

antecedent: Vec<String>

consequent: Vec<String>

support: usize

support_pct: f64

support / |transactions|, rounded to 4 decimals.

confidence: f64

sup(A∪C) / sup(A), rounded to 4 decimals.

lift: f64

confidence / (sup(C) / n), rounded to 4 decimals. 0.0 when sup(C) is unknown (consequent wasn’t a frequent itemset).

classification: String

"invariant" (conf ≥ 0.99) / "strong" (≥ 0.85) / "moderate" (≥ 0.5).
