Hi, I'm looking for any information on calculating and using Shapley Values in a TURF context. A paper was presented at an S-Plus conference about this: Conklin M., Lipovetsky S. Modern Marketing Research Combinatorial Computations: Shapley Value versus TURF Tools, Proceedings of 1998 International S-Plus User Conference, Oct. 8-9, 1998, Washington, DC, MathSo...

Hi, I am trying to compute the Shapley Values between a set of p independent variables (x1, ..., xp) and the dependent variable y to study the relationships. I believe that the package "kappalab" could be an appropriate choice. Is anybody able to give me some hints about the code I should write? Any better package? thanks i...

Dear R-helpers, I'm not a speciallist in writing complex functions, and the function still very rusty (any kind of suggestions are very welcome). I want to implement Gale-Shapley algorithm for R Language. It is based on http://www.jstor.org/stable/10.2307/2312726 Gale and Shapley (1962) , and it has evolved to http://kuznets.fas.harvard.edu/~aroth/papers/Gale%20and%20Shapley.revised.IJGT.pdf several applications in many languages, C++, JAVA, http://stackoverflow.com/que...
