The residual(e) can also be expressed with anequation. Theeis the difference between the predicted value (ŷ) and the observed value. Thescatter plotis a set of data points that are observed, while the regression line is the prediction. Residual = Observed value – predicted value e = ...
Because a linear regression model is not always appropriate for the data, you should assess the appropriateness of the model by defining residuals and examining residual plots. Residuals Residual = Observed value - Predicted value e=y-ŷ

A residual is the difference between an observed value and its predicted value in a regression model. Residuals are used to assess the fit of a regression model and form the basis for many econometric tests. Analyzing residuals helps identify patterns that indicate model deficiencies or violations ...

When a regression analysis is carried out by the least-squares method, for a model with an intercept term it is true that ∑i=1ne^in=0 which corresponds to saying that the mean value of errors is equal to zero, E(ε) = 0. Classical residuals are always associated with non-constant ...

In this post, I explain the conceptual reasons why residual plots help ensure that your regression model is valid. I’ll also show you what to look for and how to fix the problems. Residuals = Observed value – Fitted value First, let’s go over a couple of basics. ...
