A significance test for classifying arma models

Pages 305-331 | Received 14 Jun 1995, Published online: 20 Mar 2007
 

Abstract

Given that the Euclidean distance between the parameter estimates of autoregressive expansions of autoregressive moving average models can be used to classify stationary time series into groups, a test of hypothesis is proposed to determine whether two stationary series in a particular group have significantly different generating processes. Based on this test a new clustering algorithm is also proposed. The results of Monte Carlo simulations are given.
