# Simulating data from corrected DCC-GARCH process

### Description

This function simulates data from corrected DCC-GARCH process

### Usage

1 | ```
simulateCDCC(a, b, Q, a0, A, B, nobs, ncut=1000)
``` |

### Arguments

`a` |
a constant in the DCC part. |

`b` |
a constant in the DCC part. |

`Q` |
a covariance matrix of the standardized residuals with ones on diagonal |

`a0` |
a vector of constants in the GARCH part. |

`A` |
a matrix of ARCH parameter. |

`B` |
a matrix of GARCH parameter. |

`nobs` |
the number of observations to be simulated. |

`ncut` |
the number of initial entries to be discarded. Default is 1000. |

### Details

If the ARCH and GARCH parameter matrices, `A`

and `B`

,
are set as non-diagonal, the corresponding DGP allows for
interactions in conditional variances (see Nakatani and
Ter\"asvirta (2009) for instance).

For estimating a cDCC-GARCH model, `estimateCDCC`

is available.

### Value

This function returns a list with the following components.

`CDCC` |
a matrix of the simulated cDCC. |

`z` |
a matrix of the simulated standardized residuals. |

`Q` |
a matrix of the simulated Q, which is transformed into cDCC. |

`h` |
a matrix of the simulated conditional variances. |

`eps` |
a matrix of the simulated time series with cDCC-GARCH errors. |
