Abstract
We introduce here a new and general class of symmetric models, referred to as the q-symmetric family of distributions. The proposed framework includes several well-known symmetry structures, such as the classical location-symmetric, log-symmetric, and Mobius-symmetric families, as special cases. We then discuss the theoretical characterization of $q$-symmetric distributions and their relationships to existing symmetry concepts. Next, using some properties of order statistics, we characterize these distributions based on a range of information-theoretic measures associated with the probability density function. In particular, they include Shannon, Renyi, and Tsallis entropies as well as their information generating functions, extropy and weighted extropy, to enunciate some links between symmetry, information measures, and properties of order statistics.
