Expand description

The per-row expected cumulant scalars entering Lawley’s arrays.

Fields§

§k2: f64

κ₂ = E[ℓ″] (= −Fisher weight).

§k3: f64

κ₃ = E[ℓ‴].

§k4: f64

κ₄ = E[ℓ⁗].

§k2_1: f64

κ₂’ = dκ₂/dη.

§k2_11: f64

κ₂’’ = d²κ₂/dη².

§k3_1: f64

κ₃’ = dκ₃/dη.

Implementations§

Source §

impl RowKappas

Source

pub fn weighted(self, w: f64) -> RowKappas

Scale every cumulant by a prior weight w: a row observed with weight w contributes w·ℓᵢ to the log-likelihood (for binomial data w trials at the same η are exactly the sum of w independent Bernoulli rows), so all six expected derivative cumulants scale linearly in w.
