http://ask.sagemath.org/question/25506/shapley-value-calculator/?answer=48106#post-id-48106I have programmed such a website, at http://shapleyvalue.com/, which calculates the Shapley solution for up to 7 participants.
On the one hand, sometimes the best thing would be to make the effort of writing the program yourself. On the other hand, sometimes trivial inconveniences might be enough to nudge you away from using this more complex, but also very useful tool, so I think that having access to a quick calculator is also valuable.Mon, 30 Sep 2019 10:20:00 -0500http://ask.sagemath.org/question/25506/shapley-value-calculator/?answer=48106#post-id-48106Answer by NunoSempere for <p>Is there a website that can work out Shapley values for inputted numbers for me?

http://ask.sagemath.org/question/25506/shapley-value-calculator/?answer=48049#post-id-48049Such a website did not exist before, but I created it this weekend. I think it's a pity that something similar wasn't available. The url is shapley value dot com, and it currently supports up to seven players.
Ultimately, I encourage you to play around and code something yourself. But part of understanding coding is to understand their limitations, and I understand that just the trivial inconvenience of setting up an environment might be enough to desuade you from thinking in terms of Shapley values and nudge you in the direction of thinking in terms of pure counterfactuals.
I hope this helps.Wed, 25 Sep 2019 00:39:54 -0500http://ask.sagemath.org/question/25506/shapley-value-calculator/?answer=48049#post-id-48049Answer by slelievre for <p>Is there a website that can work out Shapley values for inputted numbers for me?

http://ask.sagemath.org/question/25506/shapley-value-calculator/?answer=25509#post-id-25509Sage has support for game theory, including computing Shapley values, see the [game theory documentation](http://www.sagemath.org/doc/reference/game_theory/sage/game_theory/cooperative_game.html).
You can use Sage online using the Sage cell server at [sagecell.sagemath.org](http://sagecell.sagemath.org/) or [aleph.sagemath.org](http://aleph.sagemath.org/), or using [SageMathCloud](http://cloud.sagemath.com/).
