Abstract
Accelerated Failure and Hierarchical Survival Models for Attrition Models

Survial Modelling and Individual Frailties

In this project I demonstrated how to fit a variety of hierarchical survival models in PyMC. We applied these techniques to a human resources data set attempting to measure time-to-attrition across individuals surveyed. The project is interesting within my work in Personio as example of modelling for process improvements and the measurement of drivers for efficiencies. Additionally, I think there is an interesting connection with the philosophical puzzle of the Sorites Paradox.

The project culminated in a publication to the official PyMC documentation that can be found online here or downloaded as notebook here
