摘要:

通过对Log-Lindley分布的推广,提出了一种关于(0,1)的新分布--广义Log-Lindley分布.这个新的分布被证明是一个加权Log-Lindley分布。重要的概率和统计特性已经推导出来。一个有趣的特征的加权分布的Kullback-Liebler距离和加权熵也得到了。给出了保费本金失真时保险中的一个有用结果,并用数值计算进行了验证。新的回归模型,有界响应的基础上,这个分布和他们的应用程序进行说明,考虑建模的风险管理和门诊医疗费用的另一个数据集的真实生活数据与β回归和对数林德利回归模型。两个数据集的更好拟合证明了新分布在统计建模和分析中的相关性。此外,这种概括除了增加建模的灵活性外,还保留了统计分析所需的统计量的紧凑性和易处理性,这是对数-林德利分布的一个特征。因此,广义对数林德利分布应该是一个有用的除了统计模型的从业者。

英文摘要:

A new distribution on (0, 1), generalized Log-Lindley distribution, is proposed by extending the Log-Lindley distribution. This new distribution is shown to be a weighted Log-Lindley distribution. Important probabilistic and statistical properties have been derived. An interesting characterization of the weighted distribution in terms of Kullback-Liebler distance and weighted entropy has also been obtained. A useful result in insurance for the distorted premium principal is presented and verified with numerical calculations. New regression models for bounded responses based on this distribution and their application is illustrated by considering modeling a real life data on risk management and another data set on outpatient health expenditure in comparison with beta regression and Log-Lindley regression models. Much better fits for both data sets justify the relevance of the new distribution in statistical modeling and analysis. Furthermore this generalization, apart from adding flexibility for modelling, retains the compactness and tractability of statistical quantities required for statistical analysis, which is a feature of the Log-Lindley distribution. Thus, the generalized Log-Lindley distribution should be a useful addition to statistical models for practitioners.
