Query: Growing Directed Networks: Estimation and Hypothesis Testing   Based only on the information gathered in a snapshot of a directed network,
we present a formal way of checking if the proposed model is correct for the
empirical growing network under study. In particular, we show how to estimate
the attractiveness, and present an application of the model presented in
[arxiv:0704.1847] to the scientific publications network from the ISI dataset.
