gen_pc_coef-class function

A method to generate piecewise constant coefficients

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. methods

gen_pc_coef(object, coef)

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

Arguments

• object: A simMGarch object.
• coef: A vector of coefficients.

Examples

pw.CCC.obj <- new("simMGarch")
coef.vector <- gen_pc_coef(pw.CCC.obj,c(0.2,0.4))
ts.plot(coef.vector,main="piecewise constant coefficients",ylab="coefficient",xlab="time")
