Question 1 A forecast based on the previous forecast plus a percentage of the forecast error is: Not yet answered O a. a qualitative forecast Marked out of Ob. a weighted moving average forecast 1.00 Oc. an exponentially smoothed forecast P Flag question O d. a naive forecast Oe. a moving average forecast Question 2 A fundamental distinction between trend projection and linear regression is that: Not yet answered O a. trend projection uses least squares while linear regression does not. Marked out of O b. only linear regression can have a negative slope. 1.00 P Flag question O c. linear regression tends to work better on data that lack trends. O d. trend projection uses two smoothing constants, not just one. O e. in trend projection the independent variable is time; in linear regression the independent variable need not be time, bu can be any variable with explanatory power.

Consider the following time series data: Construct a time series plot. What type of pattern exists in the data? Use a multiple regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data: Qtr1 = 1 if quarter 1, 0 otherwise; Qtr2 = 1 if quarter 2. 0 otherwise; Qtr3 = 1 if quarter 3, 0 otherwise. Compute the quarterly forecasts for next year based on the model you developed in part (b). Use a multiple regression model to develop an equation to account for trend and seasonal effects in the data. Use the dummy variables you developed in part (b) to capture seasonal effects and create a variable t such that t = 1 for quarter 1 in year 1, t = 2 for quarter 2 in year 1, … t = 12 for quarter 4 in year 3. Compute the quarterly forecasts for next year based on the model you developed in part (d). Is the model you developed in part (b) or the model you developed in part (d) more effective? Justify your answer.
