summary.arma {tseries} | R Documentation |
Methods for creating and printing summaries of ARMA model fits.
## S3 method for class 'arma': summary(object, ...) ## S3 method for class 'summary.arma': print(x, digits = max(3, getOption("digits") - 3), signif.stars = getOption("show.signif.stars"), ...)
object |
an object of class "arma" ; usually, a result of a
call to arma . |
x |
an object of class "summary.arma" ; usually, a result
of a call to the summary method for objects of class "arma" . |
digits, signif.stars |
see printCoefmat . |

further arguments passed to or from other methods. |
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.
