• ConfidenceInterval

  public ConfidenceInterval(double lowerBound,
                    double upperBound,
                    double confidenceLevel)

  Create a confidence interval with the given bounds and confidence level.

  Preconditions:

  • lower must be strictly less than upper
  • confidenceLevel must be strictly between 0 and 1 (exclusive)

  Parameters:

  lowerBound - lower endpoint of the interval

  upperBound - upper endpoint of the interval

  confidenceLevel - coverage probability

  Throws:

  MathIllegalArgumentException - if the preconditions are not met
