Enum AxisMeasure 

pub enum AxisMeasure {
    Uniform,
    Named {
        name: MeasureName,
        params: Vec<f64>,
    },
}

The measure of one continuous axis, with its parameters resolved (see MeasureName::parameter_names).

Variants

Uniform

Lebesgue measure scaled to the interval.

Named

A named distribution with its parameters.

Fields

name: MeasureName

The distribution.

params: Vec<f64>

Its parameters, in the order of MeasureName::parameter_names.

Implementations

impl AxisMeasure

pub fn from_product( measure: &ProductMeasure, axis: usize, ) -> Result<Self, String>

The measure of the axis-th continuous axis of measure: a Product is indexed, Uniform and Named apply to every axis. Named measures here carry no parameters, so they take the standard ones; a Source::Distribution supplies its own through AxisMeasure::named.

pub fn named(name: MeasureName, params: &[f64]) -> Result<Self, String>

A named measure with params resolved against the measure’s parameter table.

pub fn cdf(&self, x: f64) -> Option<f64>

The CDF of a named measure at x; None for Uniform, whose CDF depends on the interval.

pub fn quantile(&self, p: f64) -> Option<f64>

The quantile of a named measure at p ∈ [0, 1]; None for Uniform.

pub fn map_unit(&self, u: f64, interval: &Interval) -> f64

Carry a unit point u ∈ [0, 1) onto interval under this measure. Uniform is affine; a named measure inverts its CDF between the CDF values of the interval’s ends. The result lies in the interval, and an open end is never returned: a point that lands on it moves to the next float inside.

pub fn endpoint(&self, interval: &Interval, upper: bool) -> f64

The point at an end of interval under this measure: the end itself, or the next float inside when the end is open.
