Bathtub shaped failure rate distributions are of special interest in reliability
theory, survival analysis and many other fields. The so-called power Gompertz distri-
bution is one of the popular lifetime distributions that possesses the bathtub shaped
failure rate function. In this paper, we study some stochastic comparisons results for
extreme order statistics from dependent powered Gompertz distributed random vari-
ables under Archimedean copula. The study has been carried out in the sense of the
usual stochastic order and the dispersive order.
