Extended Yule-Walker identification of Varma models with single- or mixed frequency data

Zadrozny, Peter A. - 2015

Chen and Zadrozny (1998) developed the linear extended Yule-Walker (XYW) method for determining the parameters of a vector autoregressive (VAR) model with available covariances of mixed-frequency observations on the variables of the model. If the parameters are determined uniquely for available...
