Description Usage Arguments Details Value Note References See Also

These functions are S3 methods for class `"ccc"`

or `"summary.ccc"`

.

1 2 3 4 5 |

`object` |
an object of class |

`x` |
an object of class |

`digits` |
a number of digits to display. |

`...` |
optional arguments. Currently not in use. |

The function `summary.dcc()`

computes and returns a list of summary
statistics of the fitted model in `object`

of the `"dcc"`

class.

Some of the values are printed up to certain decimal places. Actual values of
individual components are displayed separately, for instance, by `summary(object)$coefficients`

.
See the **Value** section for a list of components.

For residual diagnostics, `residDiag`

carries out the Jarque-Bera test of
normality for the standardized residuals and the Ljung-Box test for serial correlations
in the standardized and squared standardized residuals.

In addition to those available in the `object`

of the `"ccc"`

class,
the following list components are added.

`nobs` |
the number of observations. |

`mu` |
the estimate of the conditional mean. |

`R` |
the estimates of the conditional correlations. Corresponding to |

`garch.par` |
the estimates of the parameters in the GARCH part. |

`coef` |
the table of all estimates with robust s.e. and associated inferencial statistics. |

`convergence` |
Integer code for the convergence status of the optimization.
See the help of |

`counts` |
a matrix containing the number of calls to the objective function
and its (numerical) gradient during the optimization. See the help
of |

`logLik` |
a value of the lig-likelihood function at the estimates. |

`AIC` |
Akaike's information criterion. |

`BIC` |
Bayesian information criterion. |

`CAIC` |
Consistent Akaike's information criterion. |

It is time consuming to implement the summary method for ‘`ccc`

’ class
object. This is because obtaining numerical derivatives, which are used for computing
the (robust) standard errors of the parameter estimates, is computationally demanding.
