detect outliers and high levarage points
Hi friends,
How to detect outliers and high leverage points for GLM ?
Could I use plot(model)
(i) "Residuals vs Fitted" graph to detect the outliers ?
(ii) "Residuals vs Leverage" graph to detect the high leverage points ?
And then remove those points from the data and re-run the model ?
