Bayesian ROC curve estimation under verification bias.
Receiver operating characteristic (ROC) curve has been widely used in medical science for its ability to measure the accuracy of diagnostic tests under the gold standard. However, in a complicated medical practice, a gold standard test can be invasive, expensive, and its result may not always be available for all the subjects under study. Thus, a gold standard test is implemented only when it i...
متن کاملMultiple imputation for correcting verification bias.
In the case in which all subjects are screened using a common test and only a subset of these subjects are tested using a golden standard test, it is well documented that there is a risk for bias, called verification bias. When the test has only two levels (e.g. positive and negative) and we are trying to estimate the sensitivity and specificity of the test, we are actually constructing a confi...
متن کاملBayesian Estimation of Combined Accuracy for Tests with Verification Bias.
This presentation will emphasize the estimation of the combined accuracy of two or more tests when verification bias is present. Verification bias occurs when some of the subjects are not subject to the gold standard. The approach is Bayesian where the estimation of test accuracy is based on the posterior distribution of the relevant parameter. Accuracy of two combined binary tests is estimated...
متن کاملA Comparison of the Effectiveness of Cognitive Bias Modification in Real and Placebo Conditions on Attentional Bias and Approach Bias in Opium Abusers
Background & Aim: Inability to control drug use is considered a core aspect of drug dependency. Part of this inability is due to cognitive biases resulting from individuals’ constant usage of drugs. The aim of the present study was to compare the effectiveness of cognitive bias modification in real and placebo conditions on attentional bias and approach bias in opium abusers. Methods: This stud...
متن کاملThe Effect of Cognitive Bias Modification in the Attention Bias of Students With Test Anxiety
Abstract Introduction: Many of the students chr('39')educational problems, including academic failure and maladaptive behaviors, stem from exam anxiety caused by studentschr('39') cognitive bias. Cognitive bias modification can reduce attention biases students to be negative. Therefore, the purpose of the present study was to investigate the effectiveness of cognitive bias modification interven...
