Generalized Birnbaum-Saunders Distribution
The two-parameter Birnbaum–Saunders (BS) distribution was originally proposed as a failure time distribution for fatigue failure caused under cyclic loading. BS model is a positively skewed statistical distribution which has received great attention in recent decades. Several extensions of this distribution with various degrees of skewness, kurtosis and modality are considered. In particular, a...
متن کاملDetermining the correlated factors of breast cancer recurrence by Poisson Beta-Weibull non- mixture cure model
Introduction: Therapies for many of diseases, especially cancer, have been improved significantly in the recent years, resulting in an increase in the number of patients who do not experience mortality. Therefore, the application of cure models is more suitable for survival analysis in this population than the usual survival models are. The aim of this study was to estimate the recurrence-free ...
متن کاملAccelerated Life Testing Model for a Generalized Birnbaum-Saunders Distribution
Fatigue failures caused by cyclic stresses are commonly modeled by Birnbaum-Saunders (B-S) and Weibull distributions. Sometimes, materials with high cycle fatigue exhibit bimodal failure rates which are difficult to model with Weibull distribution. The objective of this paper is to investigate a general Birnbaum-Saunders (GB-S) distribution which covers diverse hazard rates such as increasing, ...
متن کاملLifetime analysis based on the generalized Birnbaum-Saunders distribution
In this paper, we consider a family of generalized Birnbaum–Saunders distributions and present a lifetime analysis based mainly on the hazard function of this model. In addition, we carry out maximum likelihood estimation by using an iterative algorithm, which produces robust estimates. Asymptotic inference is also presented. Next, the quality of the estimation method is examined by means of Mo...
متن کاملGeneralized multivariate Birnbaum-Saunders distributions and related inferential issues
Birnbaum and Saunders introduced in 1969 a two-parameter lifetime distribution which has been used quite successfully to model a wide variety of univariate positively skewed data. Diaz-Garcia and Leiva-Sanchez [9] proposed a generalized BirnbaumSaunders distribution by using an elliptically symmetric distribution in place of the normal distribution. Recently, Kundu et al. [17] introduced a biva...
