kaplanmeierkaavio
Kaplan Meier kaavio, also known as a Kaplan Meier curve, is a non-parametric statistic used to estimate the survival function from lifetime data. It is particularly useful in medical research and other fields where it is important to understand the time until a specific event occurs, such as death, disease recurrence, or equipment failure. The curve plots the probability of survival over time, showing how the likelihood of the event changes as more time passes.
The Kaplan Meier method works by calculating the proportion of individuals who are still "alive" (i.e., have
The resulting Kaplan Meier curve is a step function, where the steps represent the times at which
