Enum Family 

pub enum Family {
    Poisson,
    NegativeBinomial,
    Gamma,
    Binomial,
}

Exponential family distribution for GLM.

Variants

Poisson

Poisson distribution for count data. Canonical link: log, Variance: V(μ) = μ

NegativeBinomial

Negative Binomial distribution for overdispersed count data. Canonical link: log, Variance: V(μ) = μ + α*μ² (α = dispersion parameter) Handles data where variance >> mean (overdispersion).

Gamma

Gamma distribution for positive continuous data. Canonical link: inverse, Variance: V(μ) = μ²

Binomial

Binomial distribution for binary/proportion data. Canonical link: logit, Variance: V(μ) = μ(1-μ)

Implementations

impl Family

pub const fn canonical_link(&self) -> Link

Returns the canonical link function for this family.

Trait Implementations

impl Clone for Family

fn clone(&self) -> Family

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Family

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

Formats the value using the given formatter.

impl PartialEq for Family

fn eq(&self, other: &Family) -> 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 Copy for Family

impl StructuralPartialEq for Family
