Abstract

In this paper we consider the clustering of time series arising from the class of scalar linear stochastic models. The properties and performance of several so-called model-free and model-based distances for these time series are compared on both artificial and real data sets. In particular, the inappropriateness of model-free distances to distinguish between time series of this class is shown, as well as several important differences between the model-based distances themselves.
