Figure 2. This figure shows show the sensitivity of each algorithm to source bias in the interaction matrix.

For each algorithm, we report the drop in rank induced when a node receives all of its edges from one of its neighbors. The point shows the mean correlation and the bars show plus or minus one standard deviation. The algorithms are ordered from left to right by their predictive power for the primate communication network. In the case of the primate communication network, we exhaust all possible pairs and in the case of the collaboration and functional linkage networks, we choose at random. A. Primate communication network. B. Physicist collaboration network. C. Functional linkage network of genes.
