right there's some correlation between the two, right, auto violation  the residuals  right, so where we don't have residual auto correlation which is the case here, you could actually save the residuals, perform an error less and you wouldn't find coefficient on residuals with t minus one  significant, you've got an, potentially that's what these tests for serial correlation do, right, they, you can think of them as r saving the residuals, running a, running this regression, right.
