QUESTION .1 An analyst ran three models as follows with the respective training and validation periods error values: 1. Linear Trend; Training Period RMSE =600.56_. Validation Period RMSE = 502.35 2. Exponential Trend + Seasonality; Training Period RMSE = 536.25. Validation Period RiviSE = 555.24 3. Polynomial Trend + Seasonality: Training Period Rlv'lSE = 502.69, Validation Period RMSE =?0450.25 Based on the above inron'nation. please select the right statements below. O a. An overtting issue is present in the exponential trend + seasonality model. '3 b. The exponential trend + Seasonality model has learned the systematic components better than others 0 c. The polynomial trend + Seasonality model can forecast better than others Q d. The exponential trend + Seasonality model can forecast better than other models. 0 e. An overtting issue is present in the polynomial trend + seasonality model
