A common use of a residual, also known as a raw residual, is in regression analysis. A residual is the vertical distance from a data point to the prediction line. It indicates the prediction’s error. The prediction line is essentially the average of the data points, and the residuals are...

When performing a regression analysis, if the residuals are randomly distributed around zero, it implies that: A. The model is overfitted. B. The model is underfitted. C. The model is a good fit. D. The data is incorrect. 相关知识点: ...
The distinction is most important in regression analysis, where the concepts are sometimes called the regression errors and regression residuals and where they lead to the concept of studentized residuals. 统计与优化、误差和残差是统计样本中某一要素的观测值与其“理论值”之间的偏差的两种密切相关且容易...
In linear regression the unknown true errors are often estimated by the ordinary least squares residuals. These estimates suffer from shrinkage and superimposed normality effects and may give a misleading impression of the true error distribution. A new method, RMOLS, is proposed to improve the esti...
