2. Multiple coefficient of determination Aa Aa Macroeconomics is the study of the economy as a whole. A macroeconomic variable is one that measures a characteristic of the whole economy or one of its large-scale sectors. In forecasting the sales of a product, market researchers frequently use macroeconomic variables in addition to marketing mix variables (marketing mix variables include product, price, place [or distribution], and promotion) A market researcher is analyzing an existing multiple regression model that predicts sales for...

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...

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...
