Compare empirical held-out Haufe patterns with the forward model

Compare empirical held-out Haufe patterns with the forward model

Usage

pattern_haufe(fit, X_holdout, observation_ids = NULL)

Arguments

fit

A pattern fit or view.

X_holdout

Independent rows, with all original input columns.

observation_ids

Held-out row identifiers in the same namespace as fit$training_observation_ids. Required when the fit carries those IDs.

Value

Empirical and model patterns on retained features in original units, relative Frobenius discrepancy, effective score rank, and row identifiers.

Details

Independence is a caller obligation; an ID overlap is rejected. For a rank-deficient decoder, the comparison uses the identifiable score subspace A G+ G. This is a covariance diagnostic, not an inference test.
