Enum FamilySpecKind 

pub enum FamilySpecKind {
    GaussianIdentity,
    PoissonLog,
    GammaLog,
    TweedieLog {
        p: f64,
    },
    NegativeBinomialLog {
        theta: f64,
    },
    BetaLogit {

    BinomialCLogLog,
    BinomialLatentCLogLog(LatentCLogLogState),
    BinomialSas(SasLinkState),
    BinomialBetaLogistic(SasLinkState),
    BinomialMixture(MixtureLinkState),
}

Legal-only enumeration of the (ResponseFamily, InverseLink) cells the engine recognises. LikelihoodSpec is the product type with ~40 nominal cells (8 response variants × 5 inverse-link variants), but only the cells listed here are honoured by the family math; the rest are silently masked by fallback arms. FamilySpecKind is the canonical projection used by naming, predicates, and dispatch.

Implementations

impl FamilySpecKind

pub const fn name(&self) -> &'static str

Short identifier matching the legacy LikelihoodSpec::name() strings.

pub const fn pretty_name(&self) -> &'static str

Human-readable label matching the legacy LikelihoodSpec::pretty_name() strings.

pub const fn is_binomial(&self) -> bool

pub const fn is_gaussian_identity(&self) -> bool

pub const fn is_royston_parmar(&self) -> bool

pub const fn is_latent_cloglog(&self) -> bool

pub const fn is_binomial_mixture(&self) -> bool

pub const fn is_binomial_sas(&self) -> bool

pub const fn is_binomial_beta_logistic(&self) -> bool

pub const fn supports_firth(&self) -> bool

Coarse kind-level Firth eligibility: every binomial inverse link this enum can represent (Logit/Probit/CLogLog and the stateful LatentCLogLog/SAS/Beta-Logistic/Mixture links) carries a Fisher-weight jet, so kind-level Firth support is exactly binomial membership.

The authoritative, link-resolved gate is LikelihoodSpec::supports_firth, which routes through inverse_link_has_fisher_weight_jet. Keep this in agreement with that predicate: a future binomial link without a Fisher-weight jet would make this approximation diverge and must be handled at both sites.

Trait Implementations

impl Clone for FamilySpecKind

fn clone(&self) -> FamilySpecKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FamilySpecKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FamilySpecKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FamilySpecKind

fn eq(&self, other: &FamilySpecKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FamilySpecKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
