There is a vital need for alternative methods to animal testing to assess compounds for their potency of inducing developmental neurotoxicity such as learning disabilities in children. However, data are often limited and complex in structure. Therefore, Bayesian approaches are perfect to unravel their meaning and create predictive models. In this talk, I will showcase a multilevel probabilistic model and outline how to deal with unbalanced, correlated and missing values. This presentation will be of interest for those willing to learn multilevel modelling in PyMC3, how to deal with missing values for both predictors and outcomes of data matrices, and their application to a real problem in toxicology.
Nicoleta Spînu is a PhD candidate in Computational Toxicology with a background in pharmaceutical sciences and regulatory affairs looking to have her own impact on the protection of human health while promoting animal welfare (Replacement, Reduction and Refinement of animal testing; “the 3Rs”). Research interests include the science of network and causal inference, computational modelling of chemical toxicity, and regulatory toxicology and policy making.
This is a PyMCon 2020 talk

PyMCon is an asynchronous-first virtual conference for the Bayesian community.
We have posted all the talks here in Discourse on October 24th, one week before the live PyMCon session for everyone to see and discuss at their own pace.
If you are available on October 31st you can register for the live session here!, but if you are not don’t worry, all the talks are already available here on Discourse (keynotes will be posted after the conference) and you can network here on Discourse and on our Zulip.
We value the participation of each member of the PyMC community and want all attendees to have an enjoyable and fulfilling experience. Accordingly, all attendees are expected to show respect and courtesy to other attendees throughout the conference and at all conference events. Everyone taking part in PyMCon activities must abide by the PyMCon Code of Conduct. You can report any incident through this from.
If you want to support PyMCon and the PyMC community but you can’t attend the live session, consider donating to PyMC
