Dynamic Networks

Not overly technical but thoughtful piece. I like any article that aims to deal with differing contexts over time, rately considered well in analysis.  Even in forecasts it is rare that we treat more than one dependent variable.   Look at it like a network.   This article does not do that, but it surrounds the problem.

Elements of the Theory of Dynamic Networks
By Othon Michail, Paul G. Spirakis 
Communications of the ACM, Vol. 61 No. 2, Page 72

" ... A dynamic network is a network that changes with time. Nature, society, and the modern communications landscape abound with examples. Molecular interactions, chemical reactions, social relationships and interactions in human and animal populations, transportation networks, mobile wireless devices, and robot collectives form only a small subset of the systems whose dynamics can be naturally modeled and analyzed by some sort of dynamic network. Though many of these systems have always existed, it was not until recently the need for a formal treatment that would consider time as an integral part of the network has been identified. Computer science is leading this major shift, mainly driven by the advent of low-cost wireless communication devices and the development of efficient wireless communication protocols. .... "
