summary.garch: Summarizing GARCH Model Fits

Description

Methods for creating and printing summaries of GARCH model fits.

Usage

## S3 method for class 'garch':
summary(object, \dots)
## S3 method for class 'summary.garch':
print(x, digits = max(3, getOptions("digits") - 3),
      signif.stars = getOption("show.signif.stars"), ...)

Arguments

object

an object of class "garch"; usually, a result of a call to garch.

x

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

digits, signif.stars

see print.coefmat.

...

further arguments passed to or from other methods.

Value

• A list of class "summary.garch".

Details

summary computes the asymptotic standard errors of the coefficient estimates from an outer-product approximation of the Hessian evaluated at the estimates, see Bollerslev (1986). It furthermore tests the residuals for normality and remaining ARCH effects, see jarque.bera.test and Box.test.
