For a single unit, given the ARDL coefficient vector b and its
variance V, compute the long-run coefficient on each base regressor
and the speed of adjustment, with delta-method standard errors.
.csardl_unit_lr(b, V, classify)A list with
Named numeric vector of long-run coefficients.
Variance-covariance matrix of lr_coef.
Adjustment speed \(\varphi_i = -(1 - \sum \phi_p)\).
Delta-method SE of phi.
Numeric vector: unit-level coefficients from the ARDL regression (must have names matching the regressor columns).
Numeric matrix: unit-level variance-covariance matrix.
