Survival analysis also provides tools to incorporate covariates and other predictors. In a manufactured product, such as a structural beam, at what load weight do over 1% or 5% of the units fail?.In a particular setting, such as a country, how long do people live? How does the survival rate change for different age groups such as infants, children, adults, and the elderly?.What are the lifespan characteristics of a particular species?.Research questions range from general lifespan questions about a population, such as: Often, the researcher is interested in how various treatments or predictor variables affect survival. Survival analysis is used to describe or predict the survival (or failure) characteristics of a particular population. Want to save this for later?

As the name implies, this “event” could be death (of humans with a particular disease process, crops or plants under certain conditions, animals, etc.), but it also could be any number of alternatives (the failure of a structural beam or engineering component, the reoccurrence of a disease process, etc.).įor the rest of this article, we’ll look at a fabricated example about the survival rate of domesticated dogs on different diets. Survival Analysis is a field of statistical tools used to assess the time until an event occurs.
