Ordering of rows and its effect on outcome

[tommyvcc]

Dear

I found that when I change the order of the rows according to time, the concordance and AUC change with a significant difference.

I wonder if there is a specific ordering of the data rows needed in order to get the best concordance and AUC?

What would be that order?
