    • check

      public boolean check()
      It verifies that the parameter is correct. For the normal distribution, the parameter is right if the standard deviation is greater than zero.
      Specified by:
      check in interface AutoCheck
      Specified by:
      check in interface Parameter
      Overrides:
      check in class AbstractParameter
      Returns:
      boolean indicating if the parameter is correct or not.

    • getMean

      public double getMean()
      It returns the value of the mean of the normal distribution.
      Returns:
      double with the mean of the normal distribution.

    • getStandardDeviation

      public double getStandardDeviation()
      It returns the value of the standard deviation of the normal distribution.
      Returns:
      double with the standard deviation of the normal distribution.

    • setMean

      public void setMean(double mean) throws IncorrectDistributionParameterException
      It allows the user to change the value of the mean of the normal distribution.
      Specified by:
      setMean in interface Parameter
      Overrides:
      setMean in class AbstractParameter
      Parameters:
      mean - double indicating the mean of the normal distribution.
      Throws:
      IncorrectDistributionParameterException

    • setStandardDeviation

      public void setStandardDeviation(double standardDeviation) throws IncorrectDistributionParameterException
      It allows the user to change the value of the standard deviation of the normal distribution and verifies if it is greater than zero.
      Parameters:
      standardDeviation - double indicating the standard deviation of the normal distribution.
      Throws:
      IncorrectDistributionParameterException - if the standard deviation is not greater than zero.
