Computational methods to simultaneously compare the predictive values of two diagnostic tests with missing data: EM-SEM algorithms and multiple imputation
Jose Antonio Roldan-Nofuentes
Predictive values are measures of the clinical accuracy of a binary diagnostic test, and depend on the sensitivity and the specificity of the test and on the disease prevalence amo…

Asymptotic confidence intervals for the difference and the ratio of the weighted kappa coefficients of two diagnostic tests subject to a paired design
Jose Antonio Roldan-Nofuentes, Saad bouh Sidaty-regad
The weighted kappa coefficient of a binary diagnostic test is a measure of the beyond-chance agreement between the diagnostic test and the gold standard, and depends on the sensiti…

Comparison of the likelihood ratios of two diagnostic tests subject to a paired design: confidence intervals and sample size
Jose Antonio Roldan-Nofuentes, Saad Bouh Sidaty-Regad
Positive and negative likelihood ratios are parameters which are used to assess and compare the effectiveness of binary diagnostic tests. Both parameters only depend on the sensiti…
