I am trying to run a multiple regression with a sample data belongs to a cohort of 500 subjects. My dependant variable is a psychological score (scale), independant variables are age(scale), sex(nominal) and education(scale). I run the test and Durbin-Watson was 1.99 which is good but I had 2 outliers. When I selected and removed outliers and re-run the test, Durbin-Watson became .002. Can you help me with this issue please. I dont know the reasons and how to go on. Everytime I remove an outlier shown by casewise diagnostics, DW becomes .002 or something like that.
Anybody can help me with this please?
Thank you,
