Weba dynamic hierarchical factor model that is able to decompose inﬂows in a sample of 47 economies into (i) a global factor common to all types of ﬂows and all recipient countries, (ii) a factor speciﬁc to a given type of capital inﬂows, (iii) a regional factor and (iv) a country-speciﬁc com-ponent. WebTo this end, this paper proposes a forecast-driven hierarchical factor model (FHFM) customized for mortality forecasting. It is noteworthy that hierarchical factor model appears in literature with various purposes (for example, seeMoench et al.(2013)), which are different from the aim of optimal dimension reduction for forecasting in this paper. diamond smile naniwa danshi lyrics
