Abstract: A fundamental aspect of relational data, such as from a social network, is the possibility of dependence among the relations: How A relates to B may possibly depend on how C relates to B or even how C relates to D. We investigate the possibility of estimating such dependencies from weekly international relations data among countries from 2004-2013. Such data can be represented as a multiway array, or tensor. We develop a multilinear regression model for analysis of such tensor-valued data, discuss some of its properties, and compare it to some more familiar linear regression models.
