Pre-Processing Censored Survival Data Using Inverse Covariance Matrix Based Calibration.
IEEE Transactions on Knowledge and Data Engineering(2017)
摘要
Censoring is a common phenomenon that arises in many longitudinal studies where an event of interest could not be recorded within the given time frame. Censoring causes missing time-to-event labels, and this effect is compounded when dealing with datasets which have high amounts of censored instances. In addition, dependent censoring in the data, where censoring is dependent on the covariates in t...
