The latest release of transitionMatrix library (0.4.7) expands the documentation and example set. The Academy Course PYT26038 (Analysis of Credit Migration using Python TransitionMatrix) that takes you step by step through the basics of using the library. There are five steps (course sections) that cover the main functionality of the TransitionMatrix package, with applications to a variety of synthetic and real credit data. The examples used in the course are also available in the github repository (for those who do not like to type :-) A little bonus: Sankey diagrams are very useful for the visualization of flows, especially when there is a conserved quantity. They can be tricky when some of the flows are much smaller than others such as is typically the case with credit rating transitions. In the latest release of transitionMatrix we include an example of a log-scale version of Sankey

The summer is over in the Northern Hemisphere - and what an unusual summer has it been! Worldwide the implications and challenges of adjusting to a Covid-19 pandemic are still a major issue, affecting individuals, companies and governments. The pandemic underscores the serious challenges of risk management methodologies, not unlike the serious stresses exposed during the Great Financial Crisis. If the GFC led us to formulate the Open Source Risk Modeling Manifesto, the present crisis is even more fundamental and far-reaching. It underscores how modern economies (and financial systems) have fundamental vulnerabilities that are routinely neglected even while they are real and present dangers. The shift into sustainable economies (and thus sustainable finance) will both have to accelerate and broaden in the coming years. We believe the mission of Open Risk is more than ever aligned with the required direction of travel. Welcome back to the Academy to both old and new students! Check out some new features we have just released as part of the Back-to-School 2020 and do give us some feedback how to improve the Academy!

This post aims to shed some light into the visualization process, by illustrating various distinct visualizations where we keep the dataset intentionally the same (and rather simple) and we vary the applied transforms. The result is 21 distinct ways to represent the same data, illustrating the power, flexibility, but also pitfalls of visualization

We have just released the first version of openNPL on github. openNPL is a platfrom for managing non-performing loan data. It implements the detailed templates proposed by the European Banking Authority and thus builds on best market practice. More background and details in this blog post. In due course we will add Academy courses helping along with the use of the platform and its further development.

At the OpenCPM demo instance we incorporate now open data around mobility and policy measures to tackle the Covid-19 pandemic. We plan some Academy courses around those datasets so if you are interested in the topic have a look here!
