Statistical analysis of two-parameter Birnbaum-Saunders fatigue life distribution under full sample(全样本场合下两参数Birnbaum-Saunders疲劳寿命分布的统计分析)
通过对数变换给出了求两参数Birnbaum-Saunders(BS)疲劳寿命分布BS（α，β）在全样本场合下参数的对数矩估计，并通过大量Monte-Carlo模拟比较了各种点估计方法的精度.基于对数变换通过一阶泰勒展开，将两参数BS疲劳寿命分布BS（α，β）近似看作两参数对数正态分布，由此得到了2个参数α，β的近似区间估计，通过Monte-Carlo模拟发现，所给出的近似方法比原有方法更精确.最后通过若干实例说明了方法的可行性....
