The accompanying data file contains daily sales (in $) at Café Venetian for 100 days. For cross-validation, let the training and the validation sets comprise the first 80 days and the last 20 days, respectively. pictureClick here for the Excel Data File a. Use the training set to Implement the Holt exponential smoothing method with two sets of user-supplied smoothing parameters, a=0.20 and 3-0.10 and a-0.30 and 3-0.20. Compute the resulting performance measures for the validation set. (Round final answers to 2 decimal places.). Parameters User-supplied 1 User-supplied 2 MSE because of the MAD b-1. Determine the preferred smoothing parameters for making the forecast? Forecast saies for the 101st day MAPE (N) out of 3 performance measures 4 b-2. Reestimate the preferred model with the entire data set to forecast sales for the 101st day (Round final answer to the nearest whole number.)
