I have data set contains 300 observation and when I am using the Roctab command to calculate sensitivity. and specificity the result is a long table of 300 observation each has its sensitivity, specificity and cut-point.
This an example of the code I have used used [roctab sex rocl, graph summary detail].
Is there any way or code to find out the best cut-point without searching this long table? Also, How can I calculate PPV, NPV and total accuracy using Stata.
I am using Stata Version 15.1.
Thanks for your expected help.
