A coupled model for the indegree and outdegree analysis of the web

We introduce a mixed model for web graph which simul- taneously describes the inlink and outlink distributions, by taking into account the interconnection of the two processes. We derive the expression for the steady-state distribution of indegrees (outdegrees) among vertices with fixed outde- gree (indegree) in terms of sums of Beta functions. The experimentation on subsets of the real web shows that the proposed distributions well reproduce the behaviour of the observed data.
