The main difference is that independent variables can be used to determine if one variable is the cause of changes in another, whereas predictor variables cannot.
What should d be when error terms are independent?
When the error terms are independent we expect D to be close to 2. “Small” values of D suggest that error terms tend to cluster (positive autocorrelation); “large” values of D suggest that error terms tend to alternate (+, -, +, -) (negative autocorrelation).
