Survival Analysis
Survival analysis is a branch of statistics that deals with analyzing the expected duration of time until one or more events occur, such as death in biological organisms or failure in mechanical systems. It is used to model time-to-event data, often incorporating censoring where the event of interest has not occurred for some subjects during the study period. Common applications include medical research, engineering reliability, and social sciences.
Developers should learn survival analysis when working on projects involving time-to-event prediction, such as customer churn analysis, equipment failure forecasting, or clinical trial data in healthcare applications. It is essential for handling censored data and providing insights into survival probabilities and hazard rates, making it valuable for data scientists and analysts in fields like finance, insurance, and biomedical engineering.
