Compute Group Template (v) Recovery Metrics — compute_v

Evaluates how well the estimated group-level spectral template (`object$v` from a `hatsa_projector` object) matches a true ground-truth spectral basis.

Usage

compute_v_recovery(hatsa_object, U_true, ...)

Arguments

hatsa_object: A fitted `hatsa_projector` object.
U_true: The ground-truth spectral basis (matrix, e.g., Vp x k).
...: Additional arguments passed to `vegan::procrustes`.

Value

A list containing:

correlation: Pearson correlation between the vectorized aligned estimated template and the vectorized true template.
frobenius_norm_diff: Frobenius norm of the difference between the aligned estimated template and the true template.
procrustes_result: The result of the `vegan::procrustes` call.
v_aligned: The Procrustes-aligned estimated group template.
