A PREDICTIVE APPROACH TO MODEL SELECTION AND MULTICOLLINEARITY
主张采用预测方法进行模型设定，推导了回归中包含或排除部分解释变量时均值差与协方差矩阵行列式比，并给出经济应用示例。
We argue for the adoption of a predictive approach to model specification. Specifically, we derive the difference between means and the ratio of determinants of covariance matrices when a subset of explanatory variables is included or excluded from a regression. Results for an economic application are presented as an example. © 1997 by John Wiley & Sons, Ltd.
