Shapley-shubik power distribution

The Shapley-Shubik power index for Pi is then the total number of instances in which Pi is critical, divided by n!. The Banzhaf and Shapley-Shubik power distributions for a given WVS can some-times agree, but they can also be dramatically different. (Chapter 9 of Taylor's book [5] provides an example, and also other models of power.)
