Description Usage Arguments Value Note See Also
This function computes numerical gradient of the second stage log-likelihood function of the DCC-GARCH model w.r.t. its parameters.
1 | grad.dcc2(param, dvar, d=1e-5)
|
param |
a vector of DCC parameters (2 \times 1) |
dvar |
a matrix of the standardised residuals (T \times N) |
d |
a step size for computing numerical gradient |
a vector of partial derivatives (2 \times 1)
The function is used only from dcc.estimation2
when the switch variable
gradient!=0
