component
fun componentHellinger(a: ContinuousDistributionIfc, b: ContinuousDistributionIfc, numPoints: Int = 2001): Double(source)
The Hellinger distance between two single distributions.
On the same scale-aware grid as compare, and for the same reason: this drives the component matching, so a grid that cannot resolve a narrow component pairs the wrong components with each other and every family and weight result downstream is then wrong.
