pc_acdsim-class: A method to simulate nonstationary ACD models.

Description

A S4 method that takes as an input a simACD object and outputs a simulated nonstationary ACD(1,1) model. The formulation of the of the piecewise constant ACD model is given in the simACD class.

Usage

pc_acdsim(object)
# S4 method for simACD
pc_acdsim(object)

Arguments

object

a simACD object

Value

Returns an object of simACD class containing a simulated piecewise constant ACD time series.
