Hi Jeff, 

As Philipp, I was also looking for the p-value for the goodness-of-fit of power law. While I have some problems in coding to calculate the p-value. After searching, I find a submodole named as powerlaw.regression but I can’t import it. Could you please give me some suggestion?

Moreover, I have some difficulties in understanding the Santafe paper. Here are some questions.

1. In the Table 6.1, at the column of the hat xmin, the value of the hat xim plus and minus a value ‘delta’, what’s the meaning of it, and how can we calculate it by math and python code?

2. In the Table 6.1, at the column of the hat alpha, the value of the hat alpha is with a value ‘a’, what’s the meaning of it, and how can we calculate it by math and python code?
