Description: A standard test is observed on all specimens.  We treat
        the second test (or sampled test) as being conducted on only a
        stratified sample of specimens.  We treat the total sample as
        stratified two-phase sampling and use inverse probability
        weighting.  We estimate diagnostic accuracy (category-specific
        classification probabilities; for binary tests reduces to
        specificity and sensitivity) and agreement statistics (percent
        agreement, percent agreement by category, Kappa (unweighted),
        and symmetry tests (reduces to McNemar's test for binary
        tests)).
