Shapley concentration

Shapley concentration measures how evenly information or influence is spread across different sources or parts within a system. Think of it like assessing whether a few players in a team do most of the work or if effort is shared evenly. A high Shapley concentration indicates that a small number of contributors dominate the influence, while a low value suggests a more balanced contribution among many. It helps identify whether a system's behavior results from a few key elements or a collective effort, providing insights into the distribution of importance or impact within complex networks or datasets.
