  • Method Summary

    Modifier and Type
    Method
    Description
    double
    getPValue()
    Returns the test statistic p-value.
    double
    getStatistic()
    Returns the test statistic.
    default boolean
    reject(double alpha)
    Returns true iff the null hypothesis can be rejected with 100 * (1 - alpha) percent confidence.

  • Method Details

    • getStatistic

      double getStatistic()
      Returns the test statistic.
      Returns:
      the statistic

    • getPValue

      double getPValue()
      Returns the test statistic p-value.

      The number returned is the smallest significance level at which one can reject the null hypothesis.

      Returns:
      the p-value

    • reject

      default boolean reject(double alpha)
      Returns true iff the null hypothesis can be rejected with 100 * (1 - alpha) percent confidence.

      The default implementation uses p < alpha.

      Parameters:
      alpha - Significance level of the test.
      Returns:
      true iff null hypothesis can be rejected with confidence 1 - alpha
      Throws:
      IllegalArgumentException - if alpha is not in the range (0, 0.5].
