Abstract
The main objective of this paper is to present an extension of the classical configuration model. Like a classical configuration model, the extended configuration model allows users to specify an arbitrary degree distribution. In addition, the model allows users to specify a positive or a negative assortative coefficient. We derive a closed form for the assortative coefficient of this model. We verify our result with simulations. We show that the assortative coefficient is tunable simply by changing the control parameter q.
