The Kaplan-Meier Estimate is a statistical method used in survival analysis to estimate the probability of an event, like death, over time. It's particularly useful in medical research for analyzing patient survival times and adeptly handles censored data, where the event of interest hasn't been observed for some subjects. The estimator provides a stepwise survival function, essential for evaluating treatment effectiveness in clinical trials.
