Verification bias is a well known problem when the predictive ability of a diagnostic test has to be evaluated. In this paper, we discuss how to assess the accuracy of continuous-scale diagnostic tests in the presence of verification bias, when a three-class disease status is considered. In particular, we propose a fully nonparametric verification bias-corrected estimator of the ROC surface. Our approach is based on nearest-neighbor imputation and adopts generic smooth regression models for…

bcROCsurface: an R package for correcting verification bias in estimation of the ROC surface and its volume for continuous diagnostic tests
TLDR
An R package, named bcROCsurface, is introduced, which provides utility functions for verification bias–corrected ROC surface analysis and may become an important tool for the statistical evaluation of three–class diagnostic markers in presence of verification bias.

Bias-corrected methods for estimating the receiver operating characteristic surface of continuous diagnostic tests
Verification bias is a well-known problem that may occur in the evaluation of predictive ability of diagnostic tests. When a binary disease status is considered, various solutions can be found in the
Nonparametric verification bias-corrected inference for the area under the ROC curve of a continuous-scale diagnostic test
TLDR
A fully nonparametric method for the estimation of the AUC of a continuous test under verification bias is proposed, based on nearest-neighbor imputation and adopts generic smooth regression models for both the probability that a subject is diseased and the likelihood that it is verified.
Nearest-Neighbor Estimation for ROC Analysis under Verification Bias
TLDR
A fully nonparametric method is proposed for the estimation of the ROC curve of a continuous test under verification bias that is based on nearest-neighbor imputation and adopts generic smooth regression models for both the probability that a subject is diseased and the likelihood that it is verified.
Doubly Robust Estimation of the Area Under the Receiver-Operating Characteristic Curve in the Presence of Verification Bias
TLDR
A doubly robust estimator is described that has the attractive feature of being consistent and asymptotically normal if either the disease or the selection model (but not necessarily both) is correct.
Receiver operating characteristic surfaces in the presence of verification bias
TLDR
The proposed method is applied to compare the diagnostic accuracy between mini‐mental state examination and clinical evaluation of dementia, in discriminating between three disease states of Alzheimer's disease.
Assessing accuracy of a continuous screening test in the presence of verification bias
TLDR
This work proposes and compares imputation and reweighting bias‐corrected estimators of true and false positive rates, receiver operating characteristic curves and area under the receiver Operating characteristic curve for continuous tests for screening tests for neonatal hearing loss.
A robust method using propensity score stratification for correcting verification bias for binary tests.
TLDR
A new method is proposed based on the propensity score, defined as the predicted probability of verification given the test result and observed covariates, which classifies the verified sample into several subsamples that have homogeneous propensity scores and allows correction for verification bias.
VERIFICATION BIAS — IMPACT AND METHODS FOR CORRECTION WHEN ASSESSING ACCURACY OF DIAGNOSTIC TESTS
• Sometimes it is not feasible to obtain disease status verification for all study subjects. Analysis of only those with disease ascertainment can result in biased estimates of the accuracy
Measuring and estimating diagnostic accuracy when there are three ordinal diagnostic groups.
TLDR
This article uses a receiver operating characteristic (ROC) surface to describe the probabilities of correct classifications into three diagnostic groups based on various sets of diagnostic thresholds of a test and proposes to use the entire and the partial volume under the surface to measure the diagnostic accuracy.
