A new class of extended Birnbaum–Saunders regression models is introduced. It can be applied to censored data and be used more effectively in survival analysis and fatigue life studies. Maximum likelihood estimation of the model parameters with censored data as well as influence diagnostics...

In this paper, we introduce a class of heterogeneous log-Birnbaum–Saunders regression models where both the location parameter as well as the shape parameter can be modelled in terms of covariates. The maximum likelihood estimates of parameters are derived. In addition, diagnostic measures are...
