13 In an experience the values of engine failure have been forecasted by a particular forecasting method. Considering the actual values for the engine failures for different quarters of the year, evaluate the performance of the proposed method over the error measures addressed in this chapter (E, MSE, MAE, MAPE, Bias, and TS). Do you think the proposed method is accurate? Quarter 1 2 V345678 Failures 200 250 175 186 225 285 305 190 Forecast 200.00 200.00 205.00 202.00 200.40 202.86 211.07 220.47 A
