You work for the International Monetary Fund in Washington DC, mon- itoring Singapore's real consumption expenditures. Using a sample of quarterly real consumption data (measured in billions of 2005 Singapore dollars), Yt, t = 1990.1, ..., 2006.4, you estimate the linear consumption trend model, y = Bo + B1TIME + €1, where ɛt ~ iidN(0,0²), obtain- ing the estimates Bo 0.51, B1 2.30, and ô? = 16. Based upon your estimated trend model, construct feasible point, interval and density forecasts for 2010.1.

Question
You work for the International Monetary Fund in Washington DC, mon-
itoring Singapore's real consumption expenditures. Using a sample of
quarterly real consumption data (measured in billions of 2005 Singapore
dollars), yt, t
1990.1, .., 2006.4, you estimate the linear consumption
trend model, Yt
= Bo + B¡TIM E, + E1, where & ~
iidN(0, o²), obtain-
ing the estimates Bo = 0.51, B1
2.30, and ô?
16. Based upon your
estimated trend model, construct feasible point, interval and density
forecasts for 2010.1.
Provide interval forecasts for 68% and 90% confidence levels.
