Interface MCDETest<R extends MCDETest.RankStruct>

  • Type Parameters:
    R - RankStruct or Subclass of RankStruct
    All Known Implementing Classes:
    MWPTest
    public interface MCDETest<R extends MCDETest.RankStruct>
    Interface for statistical tests for MCDEDependence. See MWPTest for an example. Implementation should contain an appropriate index structure to efficiently compute statistical test and the test itself.

      • correctedRanks

        <A> R correctedRanks​(NumberArrayAdapter<?,​A> adapter,
                     A data,
                     int len)
        Compute the corrected rank index.
        Type Parameters:
        A - Input array type
        Parameters:
        adapter - Array-like adapter
        data - Data object
        len - Length
        Returns:
        corrected ranks

      • statisticalTest

        double statisticalTest​(int start,
                       int width,
                       boolean[] slice,
                       R correctedRanks)
        Subclass must implement the computation of the statistical test, based on the slicing scheme of MCDEDependence.
        Parameters:
        start - Starting index value for statistical test
        width - Width of the slice (endindex = start + width)
        slice - An array of boolean resulting from a random slice
        correctedRanks - the precomputed index for the reference dimension
        Returns:
        a 1 - p-value
