异方差回归分析
1.
The parameters of the probabilistic model were obtained by the heteroscedastic regression analysis method based on the low cycle fatigue(LCF) test data,the fatigue life probability analysis for the pinhole of a disk was achieved by this model,and the distribution of the fatigue life of the pinhole was obtained.
针对某涡轮盘材料,在低循环疲劳试验数据的基础上应用异方差回归分析方法获得了概率模型的参数,应用该模型对涡轮盘销钉孔的低循环疲劳寿命进行了Monte-Carlo数值模拟,获到了寿命的概率分布。
2.
The stochastic expressions and probability density curves of the fatigue performance parameters were obtained by the linear heteroscedastic regression analysis of GH4133 fatigue data,and the fatigue performance parameters didn\'t follow the normal or log-normal distribution.
对GH4133材料疲劳试验数据进行线性异方差回归分析,得到了疲劳性能参数的随机表达式及概率密度曲线,各参数并不服从正态分布或对数正态分布。
6) Back-analysis and statistics regression analysis
反演及回归分析
补充资料：多元回归分析
多元回归分析
multiple regression analysis
用多元线性方程来描述和分析多个变量之间关系的统计分析方法。线性方程系数正、负表示正、负相关；系数权重比较表示这些变量在相关关系中贡献大小。但预报仅为大致的估计值。
