If a time series is covariance stationary, Delta X_t = -0.0405 - 0.4674 Delta X_t-1, what is the Mean reverting level? Hint: Mean reverting level = b_0/(1-b_1).
 
hmmm… didn’t think that was too difficult. Also, this kind of question has popped up in many places.
 
good for you…that got me the first time, as I used b1=0.4674
 
(-)0.0405/ (1-(-)0.4674)
watchout for the signs:
(-)0.0276
