Degree of freedom 11 is not active in this model and can not be restrained.这句英文翻译成中文:在这个模型中,自由度11是不活跃的,不能被约束。重点词汇释义Degree of freedom自由度not不; 不是; 几乎不; 未必,没有[用于否定后面的词或短语]active in积极于model模型; 模式; 模特儿; 典型; 做模特儿; 模仿; 制作模型,塑造; 将…做成模型; 典型的,模范的can not未可; 不能; 不可restrained克制的,节制的,受到控制的; 抑制( restrain的过去式); 管制; 制止; 控制degree of freedom 英[diˈɡri: ɔv ˈfri:dəm] 美[dɪˈɡri ʌv ˈfridəm] [词典] 自由度; [例句]That's a line. I have one degree of freedom.这是一条曲线,我有一个自由度。自由度(degree of freedom, df)在数学中能够自由取值的变量个数,如有3个变量x、y、z,但x+y+z=18,因此其自由度等于2。在统计学中,自由度指的是计算某一统计量时,取值不受限制的变量个数。通常df=n-k。其中n为样本含量,k为被限制的条件数或变量个数,或计算某一统计量时用到其它独立统计量的个数。自由度通常用于抽样分布中。
