A Model for Multivariate Non-negative Valued Processes in Financial Econometrics

Cipollini, Fabrizio; Engle, Robert F.; Gallo, Giampiero M. - Dipartimento di Statistica, Informatica, Applicazioni … - 2007

The Multiplicative Error Model introduced by Engle (2002) for non-negative valued processes is specified as the product of a (conditionally autoregressive) scale factor and an innovation process with positive support. In this paper we propose a multivariate extension of such a model, by taking...
