      Specified by:
      nullHypothesis in interface TestResult<Object>
      Returns:
      (undocumented)

    • pValue

      public double pValue()
      Description copied from interface: TestResult
      The probability of obtaining a test statistic result at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
      Specified by:
      pValue in interface TestResult<Object>
      Returns:
      (undocumented)

    • statistic

      public double statistic()
      Description copied from interface: TestResult
      Test statistic.

      (undocumented)

    • toString

      public String toString()
      Description copied from interface: TestResult
      String explaining the hypothesis test result. Specific classes implementing this trait should override this method to output test-specific information.
      Specified by:
      toString in interface TestResult<Object>
      Overrides:
      toString in class Object
      Returns:
      (undocumented)
