Description: This package provides functions to build and apply
        symmetric and asymmetric moving averages (= linear filters) for
        trend-cycle extraction. In particular, it implements several
        modern approaches for real-time estimates from the viewpoint of
        revisions and time delay in detecting turning points. It
        includes the local polynomial approach of Proietti and Luati
        (2008), the Reproducing Kernel Hilbert Space (RKHS) of Dagum
        and Bianconcini (2008) and the Fidelity-Smoothness-Timeliness
        approach of Grun-Rehomme, Guggemos, and Ladiray (2018). It is
        based on Java libraries developped in 'JDemetra+'
        (<https://github.com/jdemetra>), time series analysis software.
