static equivalent(p1: TwoClassClassificationPerformance, p2: TwoClassClassificationPerformance) → Conic[source]

Computes, on the Tile with the default parameterization, the locus of performance orderings for which the performances p1 and p2 are equivalent. This locus is a curve, a conic section.

Parameters:
Returns:

the conic section.

Return type:

Conic
