In this paper, we have constructed a random weighting statistic to approximate thedistribution of studentized least square estimator in a linear regression model with ideal accuracyo(n~(-1/2)). Thus, we have provided a more practical distribution approximating method....

问R:基于多元线性回归系数t-统计量计算Cohen's dEN在回归分析中，如果有两个或两个以上的自变量，就称为多元回归。事实上，一种现象常常是与多个因素相联系的，由多个自变量的最优组合共同来预测或估计因变量，比只用一个自变量进行预测或估计更有效，更符合实际。因此多元线性回归比一元线性回归的实用意义更大。

In linear regression, the F-statistic is the test statistic for the analysis of variance (ANOVA) approach to test the significance of the model or the components in the model. Definition The F-statistic in the linear model output display is the statistic for testing the statistical significance...
