-roctg- is a user-written program from SJ. Please remember that you
are asked to explain where user-written programs you refer to come
from.
SJ-2-4 st0025 . . . . . . . . . Two-graph receiver operating characteristic
(help roctg if installed) . . . . . . . . . . . . . M. E. Reichenheim
Q4/02 SJ 2(4):351--357
command for visualizing sensitivity and specificity curves
according to the range of values of a new diagnostic test,
given a "true" state of an event, the reference test
-roctg- is trying to -post- results to a temporary file and failing.
My guess is that you are working in a directory or folder, perhaps on
a server, in which you have no write permission, i.e. you cannot
create new files.
