Enum CovStruct 

pub enum CovStruct {
    Independence,
    Exchangeable,
}

The within-cluster working correlation structure.

Variants

Independence

Observations within a cluster are treated as uncorrelated (the working correlation is the identity). GEE then reduces to a GLM for the point estimates, but inference still uses the cluster-robust sandwich.

Exchangeable

A single common correlation ρ between every pair of observations in a cluster (compound symmetry).

Trait Implementations

impl Clone for CovStruct

fn clone(&self) -> CovStruct

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CovStruct

impl Debug for CovStruct

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

Formats the value using the given formatter.

impl PartialEq for CovStruct

fn eq(&self, other: &CovStruct) -> 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.
