Rice index

The Rice index, also known as the Rice entropy or Rice metric, is a measure used in information theory, specifically in the context of entropies of random variables. It is named after the American information theorist Hartley Rice. The Rice index contributes to assessing the diversity or distribution of information content within a dataset. In more general terms, the Rice index is often used to evaluate how evenly a particular resource or attribute is distributed across different classes or categories.
