Abstract
In the literature, Shannon differential entropy has been widely used as a measure of uncertainty or dispersion. However, there exist alternative measures such as the cumulative residual Tsallis entropy that have shown promising results in various applications. Motivated by this, we introduce a new dispersion measure, the generalized cumulative residual Tsallis entropy, and thoroughly investigate its properties. Our approach is based on the Bayes risk of the mean residual lifetime function of the proportional hazards (PH) model under a suitable prior, leading to a novel and versatile measure of dispersion. We provide analytical representations, bounds, and stochastic ordering results for the new measure, highlighting its unique properties and potential applications. To further demonstrate the practicality of the mentioned approach, we propose a nonparametric estimator of the generalized CRTE based on the empirical distribution function and apply it to image processing. The findings offer new insights into statistical inference and data analysis, emphasizing the utility of the generalized cumulative residual Tsallis entropy as a powerful tool for addressing complex problems in various domains.
