## Reparameterizing the Weibull Accelerated Failure Time Model

- how-to, intermediate

The previous example notebook on Bayesian parametric survival analysis introduced two different accelerated failure time (AFT) models: Weibull and log-linear. In this notebook, we present three different parameterizations of the Weibull AFT model.

Survival analysis studies the distribution of the time to an event. Its applications span many fields across medicine, biology, engineering, and social science. This tutorial shows how to fit and analyze a Bayesian survival model in Python using PyMC.

## Censored Data Models

This example notebook on Bayesian survival
analysis touches on the
point of censored data. *Censoring* is a form of missing-data problem, in which
observations greater than a certain threshold are clipped down to that
threshold, or observations less than a certain threshold are clipped up to that
threshold, or both. These are called right, left and interval censoring,
respectively. In this example notebook we consider interval censoring.
