Pattern quality metrics

Fields

confidence: f64

Confidence: P(consequent | antecedent) How often B happens when A happens

support: f64

Support: P(antecedent ∧ consequent) How common the pattern is overall

lift: f64

Lift: confidence / P(consequent) Strength of correlation (>1: positive, <1: negative, =1: independent)

conviction: f64

Conviction: P(A) * P(¬B) / P(A ∧ ¬B) How much more often A implies B than expected by chance

avg_time_gap: Option<Duration>

Optional: time-based metrics

time_variance: Option<Duration>
