SurvivalCurve.GetHashCode

A hash consistent with the equality, in constant time.

public int GetHashCode()

Returns — a hash over the confidence level and the number of steps.

Example — equal curves hash alike.

using Lodestar.Survival;

SurvivalCurve left = BreslowFlemingHarrington.Estimate([1, 2, 3], [true, false, true]);
SurvivalCurve right = BreslowFlemingHarrington.Estimate([1, 2, 3], [true, false, true]);

bool alike = left.GetHashCode() == right.GetHashCode();  // => True

Remarks — the four arrays share one index, so the step count stands for all of them. A curve can hold thousands of steps, which is the walk this avoids; unequal curves may collide.

Applies to — net10.0, netstandard2.0.
