Dear listers,
I just produced the weirdest ROC curve I've ever seen, and I suspect
there's a bug in roctab. The curve jumps up and down which is by
definition not possible. For your amusement and curiosity I append the
data. I am aware that as a diagnostic, x is worthless to predict y.
what I did was
insheet using roc_data.out
roctab y x, graph
Thanks,
Arnold Kester
