Examples of weka.estimators.UnivariateDensityEstimator.addValue()

weka.estimators.UnivariateDensityEstimator.addValue()
Adds a value to the density estimator. @param value the value to add @param weight the weight of the value

      // Set the number of bins appropriately
      ((UnivariateEqualFrequencyHistogramEstimator)e).setNumBins(getNumBins());


      // Initialize boundaries of equal frequency estimator
      for (int i = 0; i < m_OriginalTargetValues.length; i++) {
        e.addValue(m_OriginalTargetValues[i], 1.0);
      }
      
      // Construct estimator, then initialize statistics, so that only boundaries will be kept
      ((UnivariateEqualFrequencyHistogramEstimator)e).initializeStatistics();
