The equation for yearly sales (in '000) for a commodity with year 2000 as origin is
Y = 91.6 +28.8.X. Determine the trend equation to given monthly trend values with
January, 2001 as origin and calculate the trend for March, 2001.
Consider the following estimated trend models. Use them to make a forecast for t = 20.a. Linear Trend: yˆy^ = 12.86 + 1.09t (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
Quadratic Trend: yˆy^ = 18.58 + 0.89t − 0.01t2 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
c. Exponential Trend: ln(y)ˆln(y)^ = 1.9 + 0.07t; se = 0.05 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
