摘　　要：给出了两个相互独立但不同分布的三参数Weibull分布随机变量满足各种随机序时其分布所含参数间的相应关系.也给出了两组相互独立但不同分布的随机变量次序统计量之间的随机序关系.Two independent random variables that come from inverse Weibull distribution are compared in the usual stochastic order,likelihood ratio order,hazard ratio order and convex order. The relationship between the parameters of the cumulative distribution functions is derived when the random variables have the orders above. We also give the relationship of the order statistics that come from two groups of independent random variables.
