Research On Zero-inflated Exponential Weibull Distribution

This paper mainly studies the zero-inflated exponential Weibull distribution.Firstly,the exponential Weibull distribution and its related statistical properties are introduced.On the basis of the exponential Weibull distribution,the definition of the zero-inflated exponential Weibull distribution is given,the relevant statistical properties is given.Then,the definition of the Type ? multivariate zero-inflated exponential Weibull distribution is given,and the basic properties and statistical inference of Type ? multivariate zero-inflated exponential Weibull distribution are discussed.Finally,the extreme value distribution of zero-inflated exponential Weibull distribution is studied and its basic properties are discussed.The paper is divided into five parts:The first chapter of this paper is introduction,which firstly introduces the background significance of the research on the zero-inflated model and the exponential Weibull distribution,and the status quo of the research at home and abroad.Then the main content of this paper is introduced.In the second chapter,firstly,the exponential Weibull distribution and its related statistical properties are given.Then the basic concept of the zero-inflated exponential Weibull distribution is introduced and its relevant properties of the distribution are discussed.At the beginning of chapter three,the definition of Type ? multivariate zero-inflated exponential Weibull distribution is given,and the relevant statistical properties of the distribution are discussed.In the fourth chapter,we introduce the definition of the extreme value distribution of the zero-inflated exponential Weibull distribution,and then its relevant statistical properties are studied.In the fifth chapter,we summarize the work in this paper and put forward some further problems to be studied.
