Hi eveyone, I have a data of thousands of companies (that means that in my SAS database I have thousands of rows) and each company has its capital structure  . So I want to compute power indices of each shareholders in each company (e.g. Normalised Banzhaf index, Banzhaf index, Shapley-Shubik Indices, Shapley-Shubik indices for an "oceanic" game,  ...). It is easy to compute these indices individually, and there are many web sites that can do this "company by company", but the problem that I have is: I can't compute thousands of cases one by one and I need a code/program to do that, if possible, in one command. I use SAS to do my econometrics analysis and I have not an advanced knowledge in SAS Coding. Does somebody have a SAS code to compute power indices? Does somebody can help me to develop a code for these power indices? Thank you in advance. ... View more
