We study inference for censored survival data where some covariates are distorted by some unknown functions of an observable confounding variable in a......
Longitudinal data analysis has been very common in various fields. It is important in longitudinal studies to choose appropriate numbers of subjects a......

An issue for class-imbalanced learning is what assessment metric should be employed. So far, precision-recall curve (PRC) as a metric is rarely used i......
