Reparameterizing the Weibull Accelerated Failure Time Model
- 17 January 2023
- Category: 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.
Bayesian Survival Analysis

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.

Bayesian regression with truncated or censored data

- Category: beginner
The notebook provides an example of how to conduct linear regression when your outcome variable is either censored or truncated.
Censored Data Models
- 04 May 2022
- Category: how-to, intermediate
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.
