In the present work we discuss some aspects of modelling lifetime data employing residual entropy. Classes of life distributions with bathtub-shaped residual quantile entropy are defined and some new models are presented. Some results on quantile-based stochastic orders are attempted. We also prove characterization of a class of distributions based on relationship between residual entropy and reliability functions.
