Characterization of Order Statistics in Two Runs Using Conditional Expectation
Mohammad Reza Kazemi, Ali Akbar Jafari
The runs test is a well-known test that is used for checking independence between elements of a sample data sequence. Some of runs tests are based on the longest run and others bas…
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…
Comparing the Shape Parameters of Two Weibull Distributions Using Records: A Generalized Inference
Hojatollah Zakerzadeh, Ali Akbar Jafari
The Weibull distribution is a very applicable model for the lifetime data. For inference about two Weibull distributions using records, the shape parameters of the distributions ar…
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…
