pc_cccsim-methods function

A method to simulate nonstationary high-dimensional CCC GARCH models.

A S4 method that takes as an input a simMGarch object and outputs a simulated nonstationary CCC model. The formulation of the of the piecewise constant CCC model is given in the simMGarch class. methods

pc_cccsim(object)

## S4 method for signature 'simMGarch'
pc_cccsim(object)

Arguments

• object: a simMGarch object

Examples

pw.CCC.obj <- new("simMGarch")
pw.CCC.obj <- pc_cccsim(pw.CCC.obj)
par(mfrow=c(1,2))
ts.plot(pw.CCC.obj@y[1,],main="a single simulated time series",ylab="series")
ts.plot(pw.CCC.obj@h[1,],main="a single simulated conditional variance",ylab="variance")
