Struct LttResult 

pub struct LttResult {
    pub alpha: f64,
    pub delta: f64,
    pub threshold: f64,
    pub feasible: bool,
    pub empirical_risk: f64,
    pub n_served: usize,
    pub false_accept_rate: Option<f64>,
    pub diagnostics: Vec<LttDiagnostic>,
}

Result of LTT threshold calibration.

Fields

alpha: f64

Target served-failure rate.

delta: f64

Family-wise error rate bound (FWER ≤ δ over the qualified candidate grid).

threshold: f64

Chosen threshold λ; serve iff score ≥ λ. f64::INFINITY when no threshold is certified (infeasible, serve nothing).

feasible: bool

Whether any threshold was certified. false ⇒ target infeasible on this data.

empirical_risk: f64

Empirical served-failure rate at threshold (failures / n_served on the calibration set).

n_served: usize

Served-set size at threshold.

false_accept_rate: Option<f64>

Gate empirical false-accept rate at threshold: fraction of INCORRECT calibration items with score ≥ λ — the verifier ROC point the threshold is built on. None when the calibration set contains no incorrect items.

diagnostics: Vec<LttDiagnostic>

Per-λ diagnostics for every candidate in the grid, strictest to loosest. Includes candidates below min_n (which appear with certified: false, p_value: 1.0).
