Quizplus · Accepted Answer

The residual plot shows that there is a clear pattern in the residuals, with the spread of the residuals increasing as the predicted values increase. This suggests that there is heteroscedasticity in the data, meaning that the variance of the errors is not constant across all levels of the predictors. There is no clear evidence of autocorrelation, non-normality, or multicollinearity in the residual plot.
