question: @ Override public void addValue ( double value , double weight ) { m_WeightedSum += value * weight ; m_WeightedSumSquared += value * value * weight ; m_SumOfWeights += weight ; if ( m_TM . get ( value ) == null ) { m_TM . put ( value , weight ) ; } else { m_TM . put ( value , m_TM . get ( value ) + weight ) ; } }
target:  Adds a value to the density estimator.
