dat.kang provides an example dataset for hierarchical network meta-analysis
of diagnostic test accuracy under the missing not at random (MNAR) assumption.
The dataset is extracted from kang2013statisticalNMADTA and contains study-level
results from multiple diagnostic tests for colorectal cancer detection.
Each record corresponds to a study arm with test outcomes and missingness indicators.
data(dat.kang)A data frame with 48 observations and 8 variables:
Study identifier (integer)
Missing indicator for test 0 (1 = observed, 0 = missing)
Missing indicator for test 1 (1 = observed, 0 = missing)
Missing indicator for test 2 (1 = observed, 0 = missing)
Test 0 result (1 = positive, 0 = negative, 999 = not applicable)
Test 1 result (1 = positive, 0 = negative, 999 = not applicable)
Test 2 result (1 = positive, 0 = negative, 999 = not applicable)
Sample size for the corresponding cell
