Class for multivariate GAS model simulation.
A virtual Class: No objects may be created from it.
ModelInfo
:Object of class list
. Contains information about the multivariate GAS specification:
iT: numeric
Time length of simulated observations.
iN: numeric
Cross sectional dimension.
iK : numeric
number of (possibly) time--varying parameters implied by the distributional assumption.
vKappa numeric
vector of unconditional level for the reparametrized vector of parameters.
mA matrix
of coefficients of dimension iK x iK that premultiply the conditional score in the GAS updating recursion.
mB matrix
of autoregressive coefficients of dimension iK x iK.
Dist character
label of the conditional distribution, see DistInfo
ScalingType character
representing the scaling mechanism for the conditional score, see DistInfo
