Enum CostFunction 

pub enum CostFunction {
    L2,
    L1,
    NormalLogLikelihood,
}

Cost function type for change point detection.

Variants

L2

L2 (least squares) cost: sum of squared deviations from segment mean

L1

L1 (least absolute deviations) cost: sum of absolute deviations from segment median

NormalLogLikelihood

Normal log-likelihood cost: negative log-likelihood under Gaussian assumption

Trait Implementations

impl Clone for CostFunction

fn clone(&self) -> CostFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CostFunction

impl Debug for CostFunction

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

Formats the value using the given formatter.

impl Eq for CostFunction

impl PartialEq for CostFunction

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