广义 $ψ$-估计量的比较与相等性

Comparison and equality of generalized $ψ$-estimators

Matyas Barczy, Zsolt Páles

AI总结:

本文推导了广义 $ψ$-估计量比较与相等性的充分必要条件,并将其应用于 Bajraktarević 型、准算术型估计量及多种已知统计估计量与分布的似然方程求解。

摘要:

我们解决了 Barczy 和 Páles (2022) 提出的广义 $ψ$-估计量的比较问题。具体而言,我们推导了使一个广义 $ψ$-估计量在任意样本下小于或等于另一个 $ψ$-估计量的几个充分必要条件。我们还解决了广义 $ψ$-估计量对应的相等性问题。在应用方面,我们求解了 Bajraktarević 型和准算术型估计量的上述两个问题。我们还将结果应用于一些已知的统计估计量,如经验期望估计量、Mathieu 型估计量,以及正态分布、Beta 型、Gamma、Lomax (Pareto type II)、对数正态和 Laplace 分布下似然方程的解。

英文摘要:

We solve the comparison problem for generalized $ψ$-estimators introduced in Barczy and Páles (2022). Namely, we derive several necessary and sufficient conditions under which a generalized $ψ$-estimator less than or equal to another $ψ$-estimator for any sample. We also solve the corresponding equality problem for generalized $ψ$-estimators. For applications, we solve the two problems in question for Bajraktarević-type- and quasi-arithmetic-type estimators. We also apply our results for some known statistical estimators such as for empirical expectiles and Mathieu-type estimators and for solutions of likelihood equations in case of normal, a Beta-type, Gamma, Lomax (Pareto type II), lognormal and Laplace distributions.
