Comparison of predictive values of two diagnostic tests from the same sample of subjects using weighted least squares

Screening and diagnostic tests are important in disease prevention or control. The predictive values of positive and negative (PPV and NPV) test results are two of four operational characteristics of a screening test. We review an existing method based on the generalized estimating equation (GEE) me...
