Consider the following time series data.

Quarter Year 1 Year 2 Year 3
1 4 6 7
2 2 3 6
3 3 5 6
4 5 7 8
  1. 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. If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300)

    Value =_____ +______ Qtr1 +_______ Qtr2 +________ Qtr3 +__________  t
  2. Compute the quarterly forecasts for next year. If required, round your answers to two decimal places.

    Quarter 1 forecast =

    Quarter 2 forecast =

    Quarter 3 forecast =

    Quarter 4 forecast =
