Bayesian estimation of variance partition coefficients adjusted for imperfect test sensitivity and specificity
(2009)The variance partition coefficient (VPC) measures the clustering of infection/disease among individuals with a specific covariate pattern. Covariate-pattern-specific VPCs provide insight to the groups of individuals that ... -
Construction of Confidence Regions in the ROC Space after the Estimation of the Optimal Youden Index-Based Cut-Off Point
(2014)After establishing the utility of a continuous diagnostic marker investigators will typically address the question of determining a cut-off point which will be used for diagnostic purposes in clinical decision making. The ... -
Diagnostic and clinical significance of Crohn's disease-specific anti-MZGP2 pancreatic antibodies by a novel ELISA
(2015)Background: We developed a new IgA and IgG anti-MZGP2 antibody ELISAs based on recombinant isoform-4 of human zymogen granule protein-2 (GP2), which is the major autoantigen of Crohn's disease (CrD)-specific pancreatic ... -
The generalized Levinger transformation
(2010)In this paper, we present new results relating the numerical range of a matrix A with the generalized Levinger transformation L(A, alpha, beta) = alpha H(A) + beta S(A), where H(A) and S(A), are, respectively the Hermitian ... -
The reporting quality of studies investigating the diagnostic accuracy of anti-CCP antibody in rheumatoid arthritis and its impact on diagnostic estimates
(2012)Background: Recently anti-CCP testing has become popular in the diagnosis of rheumatoid arthritis (RA). However, the inadequate reporting of the relevant diagnostic studies may overestimate and bias the results, directing ...
