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…
Two-Sample Testing with Missing Data via Energy Distance: Weighting and Imputation Approaches
Danijel G. Aleksić, Bojana Milošević
In this paper, we address the problem of two-sample testing in the presence of missing data under a variety of missingness mechanisms. Our focus is on the well-known energy distanc…
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…
To impute or not to? Testing multivariate normality on incomplete dataset: Revisiting the BHEP test
Danijel Aleksić, Bojana Milošević
In this paper, we focus on testing multivariate normality using the BHEP test with data that are missing completely at random. Our objective is twofold: first, to gain insight into…
A Novel Test of Missing Completely at Random: U-statistics-based Approach
Danijel Aleksić
In this paper, a novel test for testing whether data are Missing Completely at Random is proposed. Asymptotic properties of the test are derived utilizing the theory of non-degener…
