Residual is the term used to describe the vertical distance between the actual and fitted values in regression analysis. It is also known as the prediction error or the difference between the observed and predicted values. The residual reflects the amount of unexplained variation in the dependent variable that is not accounted for by the independent variables. Therefore, it is an important measure of the goodness-of-fit of a regression model and can be used to assess the accuracy of predictions and to identify influential observations.
