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…
Comparing Seventeen Interval Estimates for a Bivariate Normal Correlation Coefficient
Mohammad Reza Kazemi, Ali Akbar Jafari
In this paper, we consider the problem of constructing confidence interval for the correlation coefficient in a bivariate normal distribution. For this problem, we found fifteen ap…
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…
