Consider the following Monthly time series data and Apply Holt's model to the forecast ( Carry on up to 3 decimal points: e.g., 3.215) a) Determine L0 an T0 based on the given data. (Use Excel: 3 points) b) Predict demand for February (F1) using Holt's model with =0.3,=0.6. (2 points: Don't use an Excel computer, Show your work using an equation) c) Predicted demand for March (F2) using Holt's model with =0.3,=0.6. (3 points: Don't use an Excel, Show your work using an equation) d) Suppose let L3=50 and T3 =5. Predict demand for July using Holt's model with =0.3,=0.6. (2 points)
