In this article we present a semi-parametric procedure for the decomposition of an ARFIMA model in unobserved components. The procedure relies on the DECOMEL method and yields a statistical decomposition by minimizing the Euclidean distance between the spectrum of the observed time series and the sum of the parametric spectra of the components. In particular, the paper discusses some computational issues which arise in the practical implementation of the decomposition procedure.

Abstract

In this article we present a semi-parametric procedure for the decomposition of an ARFIMA model in unobserved components. The procedure relies on the DECOMEL method and yields a statistical decomposition by minimizing the Euclidean distance between the spectrum of the observed time series and the sum of the parametric spectra of the components. In particular, the paper discusses some computational issues which arise in the practical implementation of the decomposition procedure.
