I am evaluating an arima(2,1,3) and arima(3,1,3) and notice the
log-likelihood of the restricted model is higher than the log-likelihood
of the unrestricted.
Since these are nested models, I thought the unrestricted model would have
a log-likelihood at least as large as that of the
hi: maybe it's minimizing the negative of the likeihood rather than
maximizing the likelihood ?
other than that, i don't see that being possible because of what you
said. see what
happens if you estimate an arima(1,1,3) ?
