Abstract
A popular way to measure the degree of dependence between two random variables is with mutual information, defined as the divergence between the joint and product-of- marginal distributions. We introduce an alternative measure of dependence we refer to as lautum information: the divergence between the product-of-marginal and joint distributions. Some operational characterizations and properties are provided for this alternative measure of information.
