If you have a sequence of quarterly sales data, and you built an additive HoltWinters Model. However, you nd your estimated parameters are a = 0.2, = 0.45, ",n' = 0. Starting values of seasonal factors are 2.33, 12.15. 20.39, 5.91, and the starting value of trend term is 25.44. Suppose you have L14 = 45.56, TF1 = 5.36, Stm = 531,63 = 1.00. What is the value of Tr? O 5.27 O 51.12 0 50172 O 5.45
