Recurrent event data are largely characterized by the rate function but smoothing techniques for estimating the rate function have never been rigorously developed or studied in statistical literature. This paper considers the moment and least squares methods for estimating the rate function from...

The receiver operating characteristic (ROC) curve of a likelihood-ratio function has been shown to be the highest among all transformations of continuous markers. For any sampling scheme with the same likelihoods, the induced conditional probability is derived to have the same ROC curve and is...

To increase the predictive abilities of several plasma biomarkers on the coronary artery disease (CAD)-related vital statuses over time, our research interest mainly focuses on seeking combinations of these biomarkers with the highest time-dependent receiver operating characteristic curves. An...
