Test of power law behavior in the data and likelihood ratios of alternative distributions.

<p>For each degree distribution we give a p-value for the fit to the power-law model and likelihood ratios (<i>LR</i>) for the alternatives. We also quote p-values for the significance of each of the likelihood ratio tests. Significant p-values are denoted in bold. Positive values of the likelihood ratios indicate that the power-law model is favored over the alternative. The final column of the table lists the judgment of the statistical support for the power-law hypothesis for each distribution. “Moderate” indicates that the power-law is a good fit but there are other plausible alternatives as well; “good” indicates that the power-law is a good fit and that none of the alternatives considered is plausible.
