question: public void addMeasurement ( double measurement ) { double keepConstant = 1 - mDecayConstant ; if ( mCount > mCutover ) { mValue = Math . exp ( keepConstant * Math . log ( mValue ) + mDecayConstant * Math . log ( measurement ) ) ; } else if ( mCount > 0 ) { double retained = keepConstant * mCount / ( mCount + 1.0 ) ; double newcomer = 1.0 - retained ; mValue = Math . exp ( retained * Math . log ( mValue ) + newcomer * Math . log ( measurement ) ) ; } else { mValue = measurement ; } mCount ++ ; }
target:  Adds a new measurement to the moving average.
