Hi, I am evaulating a screening programme, where there is a two-stage process: test: gives a continous score from 0 to 1. If test score is >=0.88, then the participant progresses to a definitive test to ascertain disease status disease: based on another test, the person is classifed as having t…

Hi, sorry for not getting to you earlier, your question is relevant and well written. Unfortunately this seems to me like a very tough problem that lies mostly in the design of the data collection. If you had at least some data on how disease looks like for people with lower test scores, the whole …

Hi, thanks for the reply. I had feared that this was the case. We are trying some alternative approaches, so I will post back here if any success. All the best.

I realized that I worded my reply a bit too strongly - all what I wrote is my opinion and understanding, but it is quite possible I am missing something.

Not at all - very helpful to think through these issues, and very grateful for the insights.

Thank you - that is exactly the way our thinking is evolving. ONce we have ironed out some of the code, I will post back with how we get on. Thanks!
