Method Details

epsilon

public RunComparison.Builder epsilon(double epsilon)

Minimum absolute delta below which a change counts as UNCHANGED. Default 0.001.

alpha

public RunComparison.Builder alpha(double alpha)

Significance threshold; a change is significant when its p-value is below alpha. Default 0.05.

seed

public RunComparison.Builder seed(long seed)

Seed for permutation and bootstrap procedures. Default 42.

permutationIterations

public RunComparison.Builder permutationIterations(int permutationIterations)

Permutation iteration count. Default 10000.

bootstrapIterations

public RunComparison.Builder bootstrapIterations(int bootstrapIterations)

Bootstrap iteration count. Default 10000.

itemKey

public RunComparison.Builder itemKey(Function<ItemResult,String> itemKey)

Function that derives an item-identity key from an item result. When null (default), items are paired by position index ("item-<index>").

build

public RunComparison build()

Throws:

IllegalArgumentException - if alpha is not in (0, 1), epsilon is negative, or either iteration count is less than 1
