Residual plots can be used to validate assumptions about the regression model. Figure 1: Residual plots are helpful in assessments of nonlinear trends and heteroscedasticity. A formal test of lack of ...
What are standardized residuals? How do I calculate it? How do I use it and interpret it? What are its benefits? The answers ...
