Match the below 4 2 used to control for reaction speed in exponential smoothing the average error measured as a percent of average demand 3 The running sum of forecast errors divided by the average of all forecast errors 5 used to adjust for trend in exponential smoothing the average of the absolute value of the actual forecast error 1. Mean Absolute Deviation 2. MAPE 3. Tracking Signal 4. delta 5. alpha 0/5 points What is the difference between bias and random error in forecasting? Random errors refer to short term and bias to long term Random errors refer to long term and bias to short term Random errors are smaller than bias errors Bias errors are consistently in the same direction while random errors are not 4 0/3 points
