points from @alimacher

aghaynes commented 5 years ago

also from @alimacher My last point (It would be nice if the routine also runs if the total number (i.e. number of cases plus number of non-cases) and the prevalence (of cases) are given) is actually implemented in prec_sens_spec, however it only shows the width of the larger CI (of either sens or spec). It would be nice if it shows the CI for both, sens and spec anyway, and also the CI limits (not only the width). Unfortunately, results from prec_sens_spec do not match with prec_prop. Can you have a look at that?
