Which of the followings is not used in forecasting based on the
simple exponential smoothing method?
A) The most recent forecast for the past year
B) Precise actual demand for the past year
C) The value of the smoothing constant
D) Trend for the past year
Please explain.
Homework Answers
Answer: (D) Trend for the past year
Explanation: Simple exponential smoothing, as the name suggests, is the simplest form of all the exponential smoothing forecasting methods. It is used when there is no clear trend or seasonal patterns in the given data set.
In simple exponential smoothing,
F(t+1) = 
A(t) +
(1-) F(t)
where,
F(t+1) = Forecast for the next period
A(t) = Actual demand for the past year
F(t) = Forecast for the past year
= Smoothing
constant

1: Please select the right statement(s) that apply to the exponential smoothing with trend adjustment forecasting method Select one or more: a. The exponential smoothing with trend adjustment requires the initial forecast b. The use of exponential smoothing with trend adjustment is appropriate when the underlying average of the time series is either increasing or decreasing c. α and β should be carefully selected between 0 and 1 in a way to minimize the forecasting errors d. Setting α close...

Different types of time-series forecasting models and their applicability in different organizations are given below: 1. Naive approach: In naive approach, demand for the next period is assumed to be same in the most recent period. This method can be used in economic and financial time series analysis. It can be used to forecast demand for mature products having level or seasonal demand without a trend. 2. Moving average: This method uses a number of historical data to determine the...
