gen.glambda.wge: Function to generate a g(lambda) realization

Description

This function generates a g(lambda) TVF realization as discussed in Chapter 13 of Applied Time Series Analysis with R, second edition by Woodward, Gray, and Elliott

Usage

gen.glambda.wge(n, lambda, phi =0, offset = 20, vara = 1, plot = TRUE, sn = 0)

Value

This function simply generates and (optionally plots) an ARMA realization

Arguments

n

Length of realization to be generated

lambda

The lambda involved in the g(lambda) time transformation - see Applied Time Series Analysis with R, second edition by Woodward, Gray, and Elliott

phi

Vector of AR coefficients

vara

White noise variance, default=1

offset

The offset parameter in a g(lambda) process. See section 13.2 in Applied Time Series Analysis with R, second edition by Woodward, Gray, and Elliott

plot

Logical: TRUE=plot, FALSE=no plot

sn

determines the seed used in the simulation. sn=0 produces new/random realization each time. sn=positive integer produces same realization each time
