Survival curve

A Survival curve is a statistical graph that is used in various fields such as biology, medicine, epidemiology, public health, reliability engineering, and earthquake engineering. It represents the probability that a particular individual in a particular group will survive beyond any specified time.

Overview[edit | edit source]

The survival curve is a function that maps a time period to the proportion of individuals surviving up to that time period. It is a fundamental tool in survival analysis, which is a branch of statistics that deals with death in biological organisms and failure in mechanical systems.

Construction of a Survival Curve[edit | edit source]

The survival curve is constructed using the Kaplan-Meier estimator, which is a non-parametric statistic used to estimate the survival function from lifetime data. The estimator is named after Edward L. Kaplan and Paul Meier, who each contributed to the development of the method.

Applications[edit | edit source]

Survival curves are widely used in the medical field, especially in the study of cancer and other diseases. They are also used in reliability engineering to predict the life expectancy of a product or system.
