stochastic comparisons of extreme order statistics from the generalized gompertz distribution

Stochastic comparison on order statistics from heterogeneous-dependent observations has been paid lots of attention recently. this paper devotes to investigating the ordering properties of order statistics from dependent observations. in the presence of the archimedean copula or survival copula for the random variables of samples having generalized gompertz distribution, we obtain the usual stochastic order of the sample extremes. in addition, some examples illustrating the main results are presented as well.
