Struct std_dev::regression::PowerCoefficients

pub struct PowerCoefficients {
    pub k: f64,
    pub e: f64,
    pub predictor_additive: f64,
    pub outcome_additive: f64,
}

Available on crate feature regression only.

The coefficients of a power (also called growth) function (kx^e).

Fields

k: f64

Constant

e: f64

exponent

predictor_additive: f64

If the predictors needs to have an offset applied to remove values under 1.

Defaults to 0.

outcome_additive: f64

If the outcomes needs to have an offset applied to remove values under 1.

Defaults to 0.

Trait Implementations

impl Clone for PowerCoefficients

fn clone(&self) -> PowerCoefficients

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PowerCoefficients

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

Formats the value using the given formatter.

impl Display for PowerCoefficients

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

Formats the value using the given formatter.

impl PartialEq for PowerCoefficients

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Predictive for PowerCoefficients

fn predict_outcome(&self, predictor: f64) -> f64

Calculates the predicted outcome of predictor.

fn boxed(self) -> DynModel

where Self: Sized + Display + 'static,

Put this predicative model in a box. This is useful for conditionally choosing different models.
