摘要：
An example is given to reveal the abnormal behavior of the least squares estimate of multiple regression. It is shown that the least squares estimate of the multiple linear regression may be ''improved'' in the sense of weak consistency when nuisance parameters are introduced into the model. A discussion on the implications of this finding is given.
