论文摘要
在本说明中,我们在存在其他独立变量的情况下为Cohen的$ D $引入了广义公式,从而为两组变量的位置差异提供了量度。这是通过在分区的线性回归模型中采用所谓的Frisch-Waugh-lovell定理来完成的。通过证明与适当的$ t $和$ f $统计的关系来激发概括。我们的讨论通过公共可用数据集的推断进一步说明。
In this note we introduce a generalized formula for Cohen's $d$ under the presence of additional independent variables, providing a measure for the size of a possible effect concerning the location difference of a variable in two groups. This is done by employing the so-called Frisch-Waugh-Lovell theorem in a partitioned linear regression model. The generalization is motivated by demonstrating the relationship to appropriate $t$ and $F$ statistics. Our discussion is further illustrated by inference from a publicly available data set.
