Preliminary Test and Shrinkage Estimations of Scale Parameters for Two Exponential Distributions based on Record Values
Hojatollah Zakerzadeh, Ali Akbar Jafari, Mahdieh Karimi
The exponential distribution is applied in a very wide variety of statistical procedures. Among the most prominent applications are those in the field of life testing and reliabili…
Inference on the Parameters of the Weibull Distribution Using Records
Ali Akbar Jafari, Hojatollah Zakerzadeh
The Weibull distribution is a very applicable model for the lifetime data. In this paper, we have investigated inference on the parameters of Weibull distribution based on record v…
The Beta-Gompertz Distribution
Ali Akbar Jafari, Saeid Tahmasebi, Morad Alizadeh
In this paper, we introduce a new four-parameter generalized version of the Gompertz model which is called Beta-Gompertz (BG) distribution. It includes some well-known lifetime dis…
Inference on Difference of Means of two Log-Normal Distributions; A Generalized Approach
Kamel Abdollahnezhad, M. Babanezhad, Ali Akbar Jafari
Over the past decades, various methods for comparing the means of two log-normal have been proposed. Some of them are differing in terms of how the statistic test adjust to accept…
Inference on P(Y<X) in Bivariate Rayleigh Distribution
Abbas Pak, Nayereh Bagheri Khoolenjani, Ali Akbar Jafari
This paper deals with the estimation of reliability when is a random strength of a component subjected to a random stress and follows a bivariate Rayleig…
Estimators for the Parameter Mean of Morgenstern Type Bivariate Generalized Exponential Distribution Using Ranked Set Sampling
Saeid Tahmasebi, Ali Akbar Jafari
In situations where the sampling units in a study can be more easily ranked based on the measurement of an auxiliary variable, ranked set sampling provide unbiased estimators for t…
