From the Bahrain private sector housing starts (X) for the period 1975 to 2015, Bader obtained the following regression results:
∆Xt = 20.03 – 0.174Xt-1
se = (12.50) (-2.35)
(t =) Ï„ (-2.35)
Note: The 5 percent critical Ï„ value is -2.95 and the 10 percent critical Ï„ value is -2.60
Instructions:
On the basis of these results, is the housing starts time series stationary or nonstationary? Alternatively, is there a unit root in this time series? How do you know?
This is clear, especially for the Econometrics subject.
