      The option which nature of noise distribution to choose.
      static elki.utilities.optionhandling.OptionID NOISEDISTRIBUTION_ID
      Parameter for selecting the noise distribution.
      protected double percentage
      Percentage of the variance of the random Gaussian noise generation or of the range of the uniform distribution, given the variance of the corresponding attribute in the data.
      static elki.utilities.optionhandling.OptionID PERCENTAGE_ID
      Optional parameter to specify a percentage of the standard deviation of the random Gaussian noise generation, given the standard deviation of the corresponding attribute in the original data distribution (assuming a Gaussian there).
