Missing Data, Bayesian Imputation and People Analytics with PyMC [PyCon DE & PyData Berlin 2024]

🔊 Recorded at PyCon DE & PyData Berlin 2024, 23.04.2024
https://2024.pycon.de/program/KXU7Q8/

🎓 Watch how Bayesian imputation methods in PyMC are used to uncover insights from missing data in employee engagement surveys, shedding light on causal narratives in People Analytics.

Speakers:
Nathaniel Forde

Description:
Nathaniel Forde, a Senior Data Scientist at Personio, explores various methods for missing data imputation in employee engagement survey data. Contrasting frequentist and Bayesian approaches, he emphasizes the impact of different assumptions on inferences and causal narratives, using PyMC for analysis. Forde highlights the importance of justifying assumptions like "missing-at-random" in imputation schemes, crucial in People Analytics for HR data transparency. Demonstrating Full Information Maximum Likelihood and Bayesian imputation, he showcases the benefits of Bayesian transparency over frequentist alternatives. Using PyMC, Forde maps out conditional probabilities for missing data in hierarchical organizations, emphasizing how modeling non-response bias can reveal organizational health insights. By treating missing data as a gateway to causal inference challenges, he shows how addressing data gaps can lead to concrete business solutions.
