I want to draw a histogram Z-T for each value of the couple (X-Y).
When I use thus syntax
library(lattice)

Hello
i need to simulate data for and arch and garch process, n=1000.
I've been generating arch and garch data but i can't find the way to set an
starting error, epsilon(t=0) and sigma(t=0) to run the command garchSim(). I
generated the process on Excel and i know that for the Arch process has a
I'm not quite sure what you mean, but perhaps this will help:

Sort of, I'm looking to get the nth order integral, where
