Struct SlqUnitDeflatedLogDet 

pub struct SlqUnitDeflatedLogDet {
    pub estimate: f64,
    pub std_err: f64,
    pub lambda_max_abs: f64,
    pub deflate_floor: f64,
}

Result of a unit-deflated SLQ log-determinant estimate.

The estimate is tr(φ(A)) with the unit-deflation spectral function φ(θ) = θ ≥ deflate_floor ? ln θ : 0, i.e. every eigenvalue at or below the floor is pinned to unit stiffness and contributes ln 1 = 0 — the exact matrix-free analogue of the dense ReducedSchurPolicy::EvidenceUnitDeflation convention (see #2308). lambda_max_abs and deflate_floor are reported so callers can audit the scale at which deflation kicked in.

Fields

estimate: f64

Estimate of the unit-deflated log-determinant Σ_{λ ≥ floor} ln λ.

std_err: f64

Standard error of the estimate across probes (0.0 for a single probe).

lambda_max_abs: f64

Estimated spectral radius max|λ| — the largest |Ritz value| observed across every probe. The deflation floor is relative to this scale, so it is the matrix-free stand-in for the dense path’s max|λ|.

deflate_floor: f64

The absolute deflation floor actually applied: relative_floor · lambda_max_abs · (1 − hysteresis).

Implementations

impl SlqUnitDeflatedLogDet

pub fn as_logdet(&self) -> SlqLogDet

View as a plain SlqLogDet (estimate + std-error), dropping the deflation metadata — for the evidence plumbing that only consumes the scalar log-determinant and its uncertainty band.
