Kaplan-Meier estimator
The Kaplan-Meier estimator is a statistical tool used to estimate the survival function from time-to-event data, often in clinical studies. It helps researchers understand the probability of an event, like death or failure, occurring over time in a group of subjects. The method creates a step-by-step curve that shows how many individuals are still "surviving" or have not experienced the event at different time points. This allows for visualizing and comparing survival rates across different groups, offering insights into treatment effects or disease outcomes without assuming a specific distribution of time until the event occurs.

The Kaplan-Meier estimator is a statistical method used to estimate the survival probability over time for a given group of subjects, often in medical research. It creates a step-like graph showing how many individuals remain at risk of an event (like death or failure) as time progresses. By analyzing the data, it allows researchers to understand the effectiveness of treatments or the impact of various factors on survival. This method is crucial for comparing different groups, providing insights into their long-term outcomes.
