Non-parametric estimation of cumulative (residual) extropy

Sudheesh K. K., Sreedevi E. P

摘要:

探讨了熵及其性质,以量化不确定性。本文给出了累积剩余熵和负累积熵的替代表达式。我们得到简单的累积(残差)熵估计。估计的渐近性质进行了研究。当数据是右删失时,我们也提出了新的累积(剩余)熵估计。通过蒙特卡罗模拟研究评估了估计器的有限样本性能。我们使用建议的估计分析不同的真实数据集。最后,我们得到了不同的动态和加权熵措施和可靠性概念之间的关系,这导致了与这些措施相关的几个开放的问题。

英文摘要:

Extropy and its properties are explored to quantify the uncertainty. In this paper, we obtain alternative expressions for cumulative residual extropy and negative cumulative extropy. We obtain simple estimators of cumulative (residual) extropy. Asymptotic properties of the proposed estimators are studied. We also present new estimators of cumulative (residual) extropy when the data is right censored. The finite sample performance of the estimators is evaluated through Monte Carlo simulation studies. We use the proposed estimators to analyse different real data sets. Finally, we obtain the relationship between different dynamic and weighted extropy measures and reliability concepts, which leads to several open problems associated with these measures.
