PyDTS: A Python Package for Discrete-Time Survival (Regularized) Regression with Competing Risks

Time-to-event analysis (survival analysis) is used when the outcome or the response of interest is the time until a pre-specified event occurs. Time-to-event data are sometimes discrete either because time itself is discrete or due to grouping of failure times into intervals or rounding off measurements. In addition, the failure of an individual could be one of several distinct failure types; known as competing risks (events). This work focuses on discrete-time regression with competing events. We emphasize the main difference between the continuous and discrete settings with competing events, develop a faster estimation algorithm, and present PyDTS, an open source Python package which implements our procedure and other tools for discrete-time-survival analysis with competing risks.
