摘要
The simple linear regression model tries to explain the observed values of the dependent variable in terms of those of the explanatory variable. In particular. this note considers the assumption concerning the mean square deviation of the explanatory variable. It is showed that it is not a neutral assumption because it excludes some relevant data generator processes.
