WebMar 31, 2024 · Residual Plots for Linear and Generalized Linear Models Description. Draws a plot or plots of residuals versus one or more term in a mean function and/or versus fitted values. For linear models curvature tests are computed for each of the plots by adding a quadratic term to the regression function and testing the quadratic to be zero. WebA residual plot shows the fitted values of the response variable on the x-axis and the studentized or standardized residuals on the y-axis. It can be used to check for correlated residuals or non-constant variance of the residuals, both of which would violate the residual assumptions of a linear model. It can also be used to check for outliers ...

WebR uses pass-by-value so what is sent to the function is a copy of your data.frame. (sort of, passing on some details.) So when you call the function, you need to 1) return the modified data.frame and 2) assign it or you will lose the results.
