Hi,
I usually use STATA for my data analysis, but for various reasons, ran one in SPSS first. It gave me a negative cutoff point when my data have no negative values. I re-ran in STATA and got the same AUC, but no negative cutoff, and everything else (CIs, cutoffs) are ever-so-slightly off compared to SPSS.
I'm just wondering if anyone knows why this discrepancy exists.
Thanks!
Danielle
