Weighted Cumulative Residual Mathai-Haubold Entropy
Anija C. R, Smitha S, Sudheesh K. Kattumannil
In this paper, we introduce the weighted cumulative residual Mathai--Haubold entropy and establish its fundamental properties. A dynamic version is developed, and its behavior unde…
Empirical Likelihood Inference for Sen and Sen--Shorrocks--Thon Indices
Sreelakshmi N, Saparya Suresh, Sudheesh K. Kattumannil
The Sen index and Sen-Shorrocks-Thon (SST) index are widely used measures of poverty indices. Developing reliable inference for these measures enables us to compare these measures…
A Structured Nonparametric Framework for Nonlinear Accelerated Failure Time Models (KAN-AFT)
Mebin Jose, Jisha Francis, Sudheesh Kumar Kattumannil
Accelerated failure time (AFT) models provide a direct and interpretable time-scale description of covariate effects in lifetime data analysis, but classical formulations rely on l…
A unified testing approach for log-symmetry using Fourier methods
Ganesh Vishnu Avhad, Sudheesh K. Kattumannil
Continuous and strictly positive data that exhibit skewness and outliers frequently arise in many applied disciplines. Log-symmetric distributions provide a flexible framework for…
On Relative Cumulative Residual Information Measure and Its Applications
Mary Andrews, Smitha S, Sudheesh K. Kattumannil
In this paper, we develop a relative cumulative residual information measure (RCRI) that aims to quantify the divergence between two survival functions. The dynamic relative cumula…
The Cumulative Residual Mathai--Haubold Entropy and its Non-parametric Inference
Anija C. R, Smitha S., Sudheesh K. Kattumannil
We introduce the cumulative residual Mathai--Haubold entropy (CRMHE) and investigate its properties. We then propose a dynamic counterpart, the dynamic cumulative residual Mathai--…
