Abstract

Abstract In this paper, a new compound continuous distribution named the Gompertz Fréchet distribution which extends the Frèchet distribution was developed. Its various statistical properties were also derived and estimation of model parameters was considered using the maximum likelihood estimation method. The application of the Gompertz Fréchet distribution was provided using real-life data sets and its performance was compared with Gompertz Weibull distribution, Gompertz Lomax distribution and Gompertz Burr XII distribution.

Gompertz fr分布:性质和应用
摘要本文提出了一种新的复合连续分布——Gompertz fr chet分布,它是fr chet分布的扩展。推导了模型的各种统计性质,并用极大似然估计方法对模型参数进行了估计。结合实际数据集,给出了Gompertz fracimet分布的应用,并将其性能与Gompertz Weibull分布、Gompertz Lomax分布和Gompertz Burr XII分布进行了比较。
