Class FJ_quorum.StepCDF

java.lang.Object
jline.api.fj.FJ_quorum.StepCDF
Enclosing class:
FJ_quorum
public static final class FJ_quorum.StepCDF extends Object
A discrete step function on a finite, increasing time grid.

Holds parallel arrays t[0..m-1] of abscissae and A[0..m-1] of accumulated values, with A implicitly 0 below t[0] and constant at A[m-1] above t[m-1]. When the values are a probability distribution, A is its CDF; intermediate results of the inclusion-exclusion sum are not distributions and may leave [0, 1].
