长期Fréchet分布:估计、性质及其应用

The Long Term Fréchet distribution: Estimation, Properties and its Application

Pedro Luiz Ramos, Diego Nascimento, Francisco Louzada

摘要:

本文提出了一种新的长期生存分布。所谓的长期Fréchet分布允许我们拟合一部分人口不受感兴趣事件影响的数据。该模型可用于例如临床研究中,其中一部分群体可在治疗期间治愈。它示出了一个帐户的数学性质的新的分布,如它的时刻和生存特性。同时给出了参数的极大似然估计。为了验证MLE的性能,进行了数值模拟。最后,一个重要的应用程序相关的白血病移植患者的生存时间进行了讨论,以说明我们提出的分布

英文摘要:

In this paper a new long-term survival distribution is proposed. The so called long term Fréchet distribution allows us to fit data where a part of the population is not susceptible to the event of interest. This model may be used, for example, in clinical studies where a portion of the population can be cured during a treatment. It is shown an account of mathematical properties of the new distribution such as its moments and survival properties. As well is presented the maximum likelihood estimators (MLEs) for the parameters. A numerical simulation is carried out in order to verify the performance of the MLEs. Finally, an important application related to the leukemia free-survival times for transplant patients are discussed to illustrates our proposed distribution
