Extending an Order-Statistic Characterization of the Exponential Distribution
Danijel G. Aleksić, Dušan Džamić, Bojana Milošević +1
We prove a novel characterization of the exponential distribution via a linear combination of order statistics. The theorem established herein generalizes the previous characteriza…

Testing MCAR via covariances: Extending the U-statistic framework to partially observed variables
Danijel G. Aleksić
This paper presents a generalized version of a U-statistics-based test for MCAR developed by Aleksić (2024). The proposed test, similar to the original, evaluates the MCAR assumpti…
