Suppose based on a 36-observation time series sample (from January of year 1 to December of year 3) , the estimated model is y = 3.5 + 1.2t + 0.5t2, predict the y value for May of year 4.
Homework Answers
time series sample (from January of year 1 to December of year 3)
y = 3.5 + 1.2t + 0.5t2
For May of year 4, we will use t = 36 +5 = 41
y = 3.5 + 1.2t + 0.5t2
y = 3.5 + 1.2*41 + 0.5*412
y = 3.5 + 49.2 + 840.5
y = 893.2

The index of industrial production (IPt) is a monthly
time series that measures the quantity of industrial commodities
produced in a given month. This problem uses data on this index for
the United States. All regressions are estimated over the sample
period 1986:M1 to 2013:M12 (that is, January 1986 through December
2013). Let Yt
=1200*ln(IPt/IPt-1)
Suppose that a forecaster estimates the following AR(4) model
for Yt:
Worried about a potential break, the forecaster computes a QLR
test (with 15% trimming)...
