Thanks! Reporting back the results for two models (note: "time_wk" =
"time_meaning_wks").
In model 1,? I used "time_wk" to the left of | for "CAR".
In model 2, I used "time_whtn" to the left of | for "CAR".
In both models, rho is estimated to be 1. But the likelihood profile
for rho seems ok for both models (attached).
However, in model 1, phi is estimated to be 0.1170. In model 2, phi is
estimated to be 0. In both models, the likelihood profiles for phi
seem ok.
Which phi, then, seems appropriate?
Thank you,
Stefanou
