Dear Statalist friends,
I am fairly new to stata (and ROC analysis), so please forgive me if I am slow to understand. My research involves deriving cut-off scores of the mean value of a questionnaire that is intended to be used as screening tool in practice (so my input variable is continuous and non-integer while the outcome variable is binary).
I am performing a non-parametric ROC analysis using the roctab command. I now want to derive a cut-off score for a fixed sensitivity level of 70%. I already used the cutpt command which gives me the Youden's and Liu's index and the point nearest to (0/1), however, I want to additionally provide the cut-off score at a fixed sensitivity level. Which command can I use to achieve this?
Thank you so much for your help and advice, it is very much appreciated.
