On the table you take the two values and they make up your line bare used to determine whether you accept or reject the hypothesis that auto correlation is present



0 ----- DLower --- Dupper ---- 4 - DUpper ------ 4 - DLower -----4

If your calculated D stat is below Dlower, then Positive A/C is present

Between DL and DU - inconclusive - you can't reject and can't not reject

Greater than Dupper than positive A/C is not present

And similar for negative A/c


So its

positive A/C - inconclusive - no A/C - inconclusive - negative A/C
