call to arma.
an object of class "summary.arma"; usually, a result
of a call to the summary method for objects of class "arma".

The summary method computes the asymptotic standard errors of the coefficient estimates from the numerically differentiated Hessian matrix approximation. The AIC is computed from the conditional sum-of-squared errors and not from the true maximum likelihood function. That may be problematic.
