What does this tell you about your forecasting model? O Forecasts made with Model A will be 14% more accurate than forecasts made with the Naive 1 model. O The RMSE of Model A is smaller than the RMSE for the Naive 1 model. The average error of Model A is 0.14 The mean squared error of Model A is 0.0196
