这种错误指的是将不相关的变量引入到模型中，或者某些相关的变量没有引入1

This error refers to the introduction of irrelevant variables into the model, or some related variables are not introduced13. In the feature price model, each feature is represented by an independent variable, and the features of a house are infinite, and not all features can be quantified. Some features are difficult to quantify, or only dummy variables can be used. To express, so this kind of wrong setting is unavoidable to a certain extent.

This error means that irrelevant variables are introduced into the model, or some relevant variables are not introduced 13. In the hedonic price model, each feature is represented by an independent variable, while the characteristics of a house are infinite, and not all features are energy. Some features are difficult to quantify, or can only be represented by dummy variables, so this wrong setting can not be avoided to a certain extent.<br>
