About the offer:

Praexia is a suite of scorecard modelling libraries specifically aimed at credit risk modelling. Get started with your first model using the example notebooks or make your own model using the tools in the libraries. The service operates within the Jupyter environment, where JupyterHub aids in security and access control and JupyterLab is used to create and manage your notebooks.

Intended users:

• Scorecard modellers
• Credit risk analysts and modellers
• Data scientists

What is included:

• Example notebook
This notebook illustrates the possibilities of the libraries. Use the notebook as-is, or modify it, to create your first scorecard model.
• Access to the libraries
