| Abstract: | Considering two sets of independent samples from heterogeneous Gompertz distribution,we provide some comparisons including the reversed failure rate order,the dispersive order and the convex transform order between the smallest order statistics.In addition,we also compare the largest order statistics in the sense of the usual stochastic order. |

| Keywords: | Gompertz distribution order statistic stochastic order majorization order |
