Web110 CHAPTER 6. ARMA MODELS 6.2 ACF and PACF of ARMA(p,q) 6.2.1 ACF of ARMA(p,q) In Section 4.6 we have derived the ACF for ARMA(1,1) process. We have used the linear process representation and the fact that γ(τ) = σ2 X∞ j=0 ψjψj+τ. We have calculated the coefﬁcients ψj from the relation ψ(B) = θ(B) φ(B), http://feldman.faculty.pstat.ucsb.edu/174-03/lectures/l8-9.pdf
