【摘要】 将二元威布尔分布转化为二元极值分布,威布尔分布形状参数相等的检验转化为极值分布尺度参数相等的检验,给出了当相关参数θ=0.2,0.5,0.8,1时,检验统计量的模拟分位数和统计量的功效,然后就独立情况与基于简单线性无偏估计(GLUE)和最佳线性无偏估计(BLUE)给出的统计量进行比较.最后给出一个实例.更多还原

【Abstract】 The test of shape parameter of bivariate Weibull distribution is converted into the test of scale parameter of bivariate extreme value distribution.The article shows the simulated quantile and the effect of statistics when dependent parameter θ=0.2, 0.5, 0.8, 1, then compares new statistics with known statistics derived from GLUE and BLUE when θ is equal to one. Finally an illustration to show their application is given.更多还原
