Comment(by josefpktd):

 this needs a license check,

 from fastkendalltau.py

 "Inspired by the Java implementation part of the it.unimi.dsi.law package
 (http://law.dsi.unimi.it/)"

 which is GPL code
 http://law.dsi.unimi.it/index.php?option=com_content&task=view&id=21&Itemid=42

 The algorithm has been published but, if the implementation is based on
 the Java implementation, then this wouldn't be license compatible with
 scipy.

 also the copyright says public domain
