This paper extends the family of smooth transition autoregressive (STAR) models by proposing a speci.cation in which … within a regime switching framework, but in contrast to the time varying STAR (TV-STAR) speci.cation introduced by Lundbergh … et al (2003), structural change in our random walk STAR (RW-STAR) setting follows a stochastic process rather than a …
