WebFeb 1, 2024 · The results show that cointegrated system estimation may proceed under certain conditions in a general I (1) cointegrated system in the presence (and without prior knowledge) of multicointegration. To define multicointegration for weakly dependent data, we take the triangular representation of a linear cointegrating relationship. WebBoth in VECM CVARMA and in DFM, the underlying processes are cointegrated; thus there actually are fewer (unobserved) integrated time series components than there are observed endogenous variables. The components are modelled either implicitly (in VECM CVARMA) or explicitly (in DFM). hovding ship
