4) Which of the following is relatively easier to estimate in time series modeling? A) Seasonality B) Cyclical C) No difference between Seasonality and Cyclical 5) The below time series plot contains both Cyclical and Seasonality component. 500- 400- 300- 200어 1950 1952 1954 1956 1958 A) TRUE B) FALSE 6) Sum of weights in exponential smoothing is A) <1 B)1 C) >1 7) The last period's forecast was 70 and demand was 60. What is the simple exponential smoothing forecast with alpha of 0.4 for the next period?
