Basic Question 0 of 7
If we use an AR (1) model to specify a time series (quarterly data), the correct equation that includes a seasonal lag is:
B. xt = b0 + b1 xt-1 + b2 xt-4 + εt.
C. xt = b0 + b1 xt-1 + b2 xt-4.
A. xt = b0 + b1 xt-1 + εt.
B. xt = b0 + b1 xt-1 + b2 xt-4 + εt.
C. xt = b0 + b1 xt-1 + b2 xt-4.

| akirchner1 | 'Quarterly' is key here which is why t-4 is used. Can't forget the error term though. |
I was very pleased with your notes and question bank. I especially like the mock exams because it helped to pull everything together.
