A Conditional Quantile Approach to Vector-Valued Bivariate Lorenz Surfaces: Properties and Applications

Shifna P R, S. M. Sunoj

The Lorenz curve is a fundamental tool for measuring inequality, but its extension to multivariate settings remains challenging due to the complex dependence structure among variab…

Fractional Cumulative Residual Entropy in the Quantile Framework and its Applications in the Financial Data

Iona Ann Sebastian, S. M. Sunoj

Fractional cumulative residual entropy (FCRE) is a powerful tool for the analysis of complex systems. Most of the theoretical results and applications related to the FCRE of the li…
