powerlaws's Issues

Add parallel calculation of the significance

The significance is currently calculated serially. I think the calculation could be much faster if it is calculated in parallel.

How to add Data2Semantics/powerlaws in the pom.xml?

Hi ,there, I want user powerlaws to caculate the network metric, I found that when I add it in the pom.xml file it went wrong

 <dependency>
        <groupId>data2semantics</groupId>
        <artifactId>powerlaws</artifactId>
        <version>0.0.1-SNAPSHOT</version>
 </dependency> 

have not published?

Off-by-one error in Continuous.p?

According to the paper of Clauset et al. (both the 2007 and the 2009 version), the PDF of a continuous power-law distribution is defined as (alpha-1)/x_min * (x/x_min)^(-alpha). The current implementation (line 43 of Continuous.java) does not match that definition:
return (exponent() / xMin()) * Math.pow(x / xMin(), -exponent());
Should it be changed to:
return ((exponent() - 1.0) / xMin()) * Math.pow(x / xMin(), -exponent());
?
