Abstract: Abstract In this paper, relative behavior of two frailty models with different frailty variables and a common baseline variable are considered. We show that, under some conditions on frailty variables, the ratio of the hazard rate (mean residual life) functions of two frailty models is increasing. Finally, some applications are examined to validate the obtained results.
