gen_pc_coef-class: A method to generate piecewise constant coefficients

Description

An auxilliary method to calculate piecewise constant coefficients for a user-specified vector of coefficients. The change-points are controlled by the changepoints slot in the simMGarch object.

Usage

gen_pc_coef(object, coef)
# S4 method for simMGarch
gen_pc_coef(object, coef)

Arguments

object

A simMGarch object.

coef

A vector of coefficients.
