Recently, reproducing kernel Hilbert spaces have been introduced to provide a common approach for studying several nonparametric estimators used for smoothing functional time series data (Dagum and Bianconcini, 2006 and 2008). The reproducing kernel representation is based on the derivation of...

business cycle frequencies strongly rely on the correct detection of the number of common stochastic trends (co-integration). Standard techniques for the determination of the number of common trends, such as the well-known sequential procedure proposed in Johansen (1996), are based on the...

Real-time signal extraction (RTSE) concerns the determination of optimal asymmetric filters towards the end of a time series where - otherwise desirable - symmetric filters cannot be applied anymore. The attractiveness of this particular estimation problem resides in the generality of its scope....
