摘要

为建模数据选择最合适的统计分布是非常重要的。一般来说，新的分布更灵活地模拟具有高度偏度和峰度的真实数据。本文定义了一种新的单参数寿命分布，即加权林德利分布。研究了它的一些基本性质。一些经典的估计方法和贝叶斯估计方法被用来估计它的参数。通过图形模拟研究了这些估计器的行为。通过对一个实际数据集的分析，验证了新加权林德利分布的灵活性。

A New Weighted-Lindley Distribution: Properties, Classical and Bayesian Estimation with an Application

The choice of the most suitable statistical distribution for modeling data is very important. Generally, the new distributions are more flexible to model real data that present a high degree of skewness and kurtosis. In this paper, we define a new one-parameter lifetime distribution, so-called weighted-Lindley distribution. Some of its basic properties are investigated. Some classical and Bayesian methods of estimation have been used for estimating its parameter. The behavior of these estimators were investigated by a graphical simulation study. A real data set is analyzed to investigate the flexibility of the new weighted-Lindley distribution.
