ABSTRACT
Thus far in this book, we have considered models for univariate data; that is, models which have allowed us to relate a single response to a set of one or more explanatory variables. In the rest of this book, we will assume that the response is multivariate in nature; in other words, there is more than one response process being observed simultaneously. In this book, attention will be concentrated on the modelling of data comprising two and three response processes, known as bivariate and trivariate data respectively.
