- Abstract
- The screening test is increasingly being used for predicting future disease in the person screened and has raised concerns about reliability of the result of its procedure. We propose an improved estimator of the confidence interval for the positive predictive value(PPV) in screening test by simply taking inverse transformation comparing to Gastwirth(1987) estimator and show its efficiency through the simulation study.
