With reference to exponential forecasting models, a parameter that provides the weight given to the most recent time series value in the calculation of the forecast value is known as the
smoothing constant.
moving average.
regression coefficient.
mean forecast error.

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...
Which of the following exponential smoothing constant values puts the same weight on the most recent time series value as does a 3-period moving average? a. .2 b. .25 c. .75 d. .8
1. Regression is always a superior forecasting method to exponential smoothing, so regression should be used whenever the appropriate software is available. (Points :1)TrueFalse2. Time-series models rely on judgment in an attempt to incorporate qualitative or subjective factors into the forecasting model. (Points : 1)TrueFalse3. A trend-projection forecasting method is a causal forecasting method. (Points : 1)TrueFalse4. Qualitative models attempt to incorporate judgmental or subjective factors into the forecasting model. (Points : 1)TrueFalse5. The naive forecast for the next period...
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.
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...

Examples 1,2,3 1. Beyond Tea Inc. wants to forecast sales of its menthol green tea. The company is considering either using a simple mean or a three-period moving average to forecast monthly sales. Given sales data for the past 10 months use both forecasting methods to forecast periods 7 to 10 and then evaluate each. Which method should they use? Use the selected method to make a forecast for month 11. (Show all calculations .... Please read Examples1, 2, 3...
