Enum RegressionIntervalCell 

pub enum RegressionIntervalCell {
    Finite {
        lower: f64,
        upper: f64,
    },
    Unbounded,
}

One regression interval cell.

The tagged form makes unbounded endpoints inseparable, avoiding (-inf, +inf) sentinels and half-unbounded states.

Variants

Finite

Fields

lower: f64

upper: f64

Unbounded

Implementations

pub fn endpoints(self) -> (Option<f64>, Option<f64>)

Return wire-shaped paired endpoints (None, None when unbounded).

pub fn midpoint(self) -> Option<f64>

Return a finite midpoint without overflowing endpoint addition.
