Estimation of haplotype associated with several quantitative phenotypes based on maximization of area under a receiver operating characteristic (ROC) curve

An algorithm for estimating haplotypes associated with several quantitative phenotypes is proposed. The concept of a receiver operating characteristic (ROC) curve was introduced, and a linear ...

The Predictive Receiver Operating Characteristic Curve for the Joint Assessment of the Positive and Negative Predictive Values

Binary test outcomes typically result from dichotomizing a continuous test variable, observable or latent. The effect of the threshold for test positivity on test sensitivity and specificity has been ...

Receiver Operating Characteristic Curves

In a sample of n individuals, suppose n 1 individuals are observed to have a certain condition or event. Let this group be denoted by C 1, and let the group of the remaining n 2 =n-n 1 individuals who ...
