Dear Sir,
I currently use STATA 11.2 and I have installed the midas command

I have this dataset:

tp	fp	fn	tn

27	8	4	35
19	5	12	41
18	6	5	13
50	9	7	35
35	5	22	40
18	3	5	30
20	5	10	12
48	5	28	15
28	4	5	16

However, with the command: midas tp fp fn tn(pred), I'm unable to obtain a sroc graph with the 95% prediction contour

Using the (both) option only the 95% Confidence Contour is cleary detectable in the graph.
Many thanks in advance

Sincerely
