A large value of the residual (positive or negative) shows the model does not fit the particular data point. The pattern of the residuals will often reveal the inadequacy of the fitted model. A plot of the residuals, often called the residual plot, is an important tool in regression model building. In this article we will concentrate on the role of residuals in regression analysis.

摘要

A large value of the residual (positive or negative) shows the model does not fit the particular data point. The pattern of the residuals will often reveal the inadequacy of the fitted model. A plot of the residuals, often called the residual plot, is an important tool in regression model building. In this article we will concentrate on the role of residuals in regression analysis.
