Enum TwoFoldType 

pub enum TwoFoldType {
    Pooled,
    Neumark,
    Cotton,
    Reimers,
    SelfSubmitted(f64),
}

Weighting scheme for the non-discriminatory coefficient vector β* used by the two-fold (“pooled”) decomposition. Mirrors the reference two_fold_type options.

Variants

Pooled

β* from OLS on the full sample including the group indicator; the indicator’s coefficient is dropped before applying β*.

Neumark

β* from OLS on the full sample excluding the group indicator (the “Neumark” pooled model).

Cotton

Cotton (1988) sample-size weighting: β* = (n_f β_f + n_s β_s) / (n_f + n_s).

Reimers

Reimers 50/50 weighting: β* = ½ (β_f + β_s).

SelfSubmitted(f64)

User-supplied weight w on the larger-mean group: β* = w β_f + (1 − w) β_s.
