It's a bit difficult to say, isn't it? The headline is using the term accuracy correctly, the reader might be ascribing the meaning you are to it, especially if they are non technical. As was the parent comment.
My goal in pointing out the difference was not to be snarky. It was to point out the very real statistical consequences. Any model can be accurate on a sufficiently biased dataset, but what matters once a screening test hits the real world are the precision (positive predictive value) and negative predictive value. These are the hurdles that the test will have to pass to see widespread adoption.
- jacquesm 3y agoExactly. This is the real test and so far we simply do not know the answer. It's a nice first step but the headline is simply not justified. But whether solar power, wind power or cancer it's 99.99% of the time (possibly more nines) far less impressive by the time all of the data is in. And that's fine, but headline writers seem to be stuck in a hype cycle.
