Horizontal b. Use the following dummy variables to develop an estimated regression 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. Enter negative values as negative numbers. = + Qtr1 + Qtr2 + c. Compute the quarterly forecasts for next year.
