Functions

beta_logistic_inverse_link_jet

Beta-Logistic inverse-link jet for: u = logistic(eta) a = exp(log_shape_center - epsilon), b = exp(log_shape_center + epsilon) mu = I_u(a, b)

beta_logistic_inverse_link_jetwith_param_partials

beta_logistic_inverse_link_pdffourth_derivative

Fifth derivative of the beta-logistic inverse-link CDF (= 4th deriv of PDF).

beta_logistic_inverse_link_pdfthird_derivative

component_inverse_link_jet

inverse_link_jet_for_family

inverse_link_jet_for_family_public

EXACT public inverse-link jet for response-scale prediction outputs.

inverse_link_jet_for_inverse_link

Central family-aware inverse-link jet dispatch.

inverse_link_mu_d1_for_inverse_link

Specialized (mu, d1) inverse-link evaluation that skips the d2/d3 polynomial chain used by the full jet. Numerical semantics are preserved: the returned mu and d1 are bit-identical to the corresponding fields of inverse_link_jet_for_inverse_link(link, eta)? for every supported link.

inverse_link_pdffourth_derivative_for_inverse_link

Fifth derivative of the inverse-link CDF (= fourth derivative of the PDF).

inverse_link_pdfthird_derivative_for_inverse_link

logit_inverse_link_jet5

mixture_inverse_link_jet

mixture_inverse_link_jetwith_rho_partials

Computes mixture jet and exact partial derivatives wrt free softmax logits.

mixture_inverse_link_jetwith_rho_partials_into

Computes mixture jet and writes exact rho partial jets into out (length >= K-1). This avoids heap allocation in hot loops.

sas_inverse_link_jet

SAS inverse-link jet for: mu(eta) = Phi(sinh(delta * asinh(eta) - epsilon)), delta = exp(B * tanh(log_delta / B)), B = SAS_LOG_DELTA_BOUND.

sas_inverse_link_jetwith_param_partials

sas_inverse_link_pdffourth_derivative

Fifth derivative of the SAS inverse-link CDF (= fourth derivative of the PDF).

sas_inverse_link_pdfthird_derivative

sas_link_state_from_raw

Construct SAS state from raw optimizer parameters using the same bounded transform used everywhere in fitting/evaluation.

softmax_last_fixedzero

softmaxwith_jacobian_last_fixedzero

Returns softmax weights and Jacobian wrt free logits (last logit fixed at zero). Jacobian shape is (K, K-1): d pi_k / d rho_j.
