| dcc.estimation1 {ccgarch} | R Documentation |
This function carries out the first stage (volatility part) estimation of the (E)DCC-GARCH model.
dcc.estimation1(dvar, a, A, B, model)
dvar |
a matrix of the observed residuals (T times N) |
a |
a vector of constants (N times 1) |
A |
an ARCH parameter matrix (N times N) |
B |
a GARCH parameter matrix (N times N) |
model |
a character string describing the model. "diagonal" for the diagonal model and "extended" for the extended (full ARCH and GARCH parameter matrices) model |
a list of the estimation results. See the explanations in optim.
