sim.pw.ar2 {wbsts}

Simulation of a piecewise constant AR(2) model

Description

The function simulates a piecewise constant AR(2) model with multiple change-points

Usage

sim.pw.ar2(N, sd_u, b.slope, b.slope2, br.loc)

Arguments

N

Length of the series

sd_u

A vector of the innovation standard deviation for every segment

b.slope

A vector of the AR(1) coefficients

b.slope2

A vector of the AR(2) coefficients

br.loc

A vector with the location of the change-points

Value

A simulated series

Examples

 
cps=c(512,754)
y=sim.pw.ar2(N =1024,sd_u = 1,b.slope=c(0.9,1.68,1.32),
b.slope2 = c(0.0,-0.81,-0.81),br.loc = cps)[[2]]
ts.plot(y)
