Question 1

What is Survival Analysis?

Accepted Answer

Survival Analysis is a statistical method used to analyze time-to-event data. It is particularly useful in studying the duration of time until an event of interest occurs, such as death, failure, or recovery. This analysis allows researchers to understand the probability of an event happening at a certain time, and how different factors may influence the time to event occurrence. Survival analysis techniques are widely used in various fields, including biostatistics, epidemiology, engineering, economics, and social sciences, to name a few.
