非归一化参数模型的最小$L^q$ -距离估计

Minimum $L^q$-distance estimators for non-normalized parametric models

Steffen Betsch, Bruno Ebner, Bernhard Klar

摘要:

提出并研究了正半轴上光滑密度函数模型参数的一种新的估计方法。该程序是基于最近推出的表征结果的相应的概率分布,并被归类为最小距离估计,作为一个距离函数的$L^q$规范。在整个过程中,我们严格处理这些隐含定义的估计的存在性和可测性问题。此外,我们提供了一个共同的渐近设置的一致性结果,并比较我们的新方法与经典的估计指数,瑞利,和伯尔型XII分布在蒙特卡洛模拟研究。我们还评估了非归一化模型的指数多项式族的背景下,不同的估计的性能。

英文摘要:

We propose and investigate a new estimation method for the parameters of models consisting of smooth density functions on the positive half axis. The procedure is based on a recently introduced characterization result for the respective probability distributions, and is to be classified as a minimum distance estimator, incorporating as a distance function the $L^q$-norm. Throughout, we deal rigorously with issues of existence and measurability of these implicitly defined estimators. Moreover, we provide consistency results in a common asymptotic setting, and compare our new method with classical estimators for the exponential-, the Rayleigh-, and the Burr Type XII distribution in Monte Carlo simulation studies. We also assess the performance of different estimators for non-normalized models in the context of an exponential-polynomial family.
