Answer question 6-10 please!

6. Which of the following is not a quantitative technique for evaluating the accuracy of a time-series modeling technique? a. Constructing line graphs of the data. b. The mean absolute deviation. c. The mean absolute percent error d. The root mean square error A technique that analyzes past behavior of a time-series variable to predict the future is referred to as a. a regression model. b. a seasonal model. c. a past performance model. d. an extrapolation model. 7. 8. How is mean absolute deviation calculated? It It In the formula for MAD, MAPE, and MSE, the Yt and Y terms represent a the actual and mean values, respectively b. the actual and forecasted values, respectively c. the forecasted and actual values, respectively d. the predicted and forecasted values, respectively 9. 10. The general form of an extrapolation model for time-series analysis is dÝ,.,-4%Ý,.lho )

Explanation / Answer

6. (A) Constructing the line graphs of the data.... because MAD, MSE and MAPE are the quantitative techniques

7. (D) Extrapolation Model .....is referred to as predicting the future with the help of the existing data

8. (A) Sigma of "|Y-Y^| / n"

9. (A) The actual and mean values respectively

10. (D)
