used to estimate a linear trend model as Tˆt = 164.90 + 1.09t. In
addition, quarterly seasonal indices are calculated as Sˆ1 = 0.88,
Sˆ2 = 0.94, Sˆ3 = 1.16, and Sˆ4 = 1.12. a-1. Interpret the first
quarterly index. In other words, what is the value of the series in

The table below shows semi-annual demand (in thousands) for
Shidgets (they're like Widgets, only quieter). A linear trend has
been estimated using this data set with t = 1 for 1990.1
and t = 8 for 1993.2. It has an intercept of 0.76 and a
slope of 0.20:
Y= 0.76+0.20T
Use the ratio-to-trend method to calculate seasonal adjustment
factors for the first and second half of the year and then forecast
the level of demand for 1995.1. Note: Round all...
