Description

This function simulates data from a DCC-GARCH process

Usage

1
simulateDCC(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.

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 DCC-GARCH model, estimateDCC is available.

Value

This function returns a list with the following components.

DCC

a matrix of the simulated DCC

z

a matrix of the simulated standardized residuals

Q

a matrix of the simulated Q_t, which is transformed into DCC.

h

a matrix of the simulated conditional variances.

eps

a matrix of the simulated time series with DCC-GARCH errors.
