If your goal is to use a fitted model to do prediction, then you cannot use robust standard errors because you need to make the assumption of normality as well as homoscedasticity. This is not how most people use linear models. Most use linear models to test for statistical significance of model parameters.

Web23 de mar. de 2024 · Step 5: Interpret the Q-Q Plot. The idea behind a Q-Q plot is simple: if the residuals fall along a roughly straight line at a 45-degree angle, then the residuals are roughly normally distributed. We can see in our Q-Q plot above that the residuals tend to deviate from the 45-degree line quite a bit, especially on the tail ends, which could be ...
