Credit Migrations using TransitionMatrix

Reading Time: 1 min.
Summary This course is a CrashProgram (short course) in the use of Python and the package TransitionMatrix for analysing credit migration data. Requirements The course is at a medium technical level. It requires some familiarity with python (and a working installation that includes the common numpy/scipy libraries). On the risk modelling side it requires knowledge of basic credit rating migration concepts. Outcomes Step by step we build the knowledge required to use python to analyse credit migration data:

Input-Output Models with Python

Risk Data Review

Reading Time: 1 min.
Summary This course is a CrashProgram (short course) introducing the concept of a structured review of risk data. Outcomes Step by step we build the knowledge required to review the suitability of data for a given purpose and how to report the findings. We learn the concept of Data Provenance We get a first exposure to the different levels of Data Validation as recommended by EuroStat We summarize our findings in a mock report written in Markdown format Course Level and Type The course is at an introductory technical level.
Class Inheritance in Data Science

Class Inheritance in Data Science

Object-oriented programming and techniques (OOP) such as using classes and inheritance are common in many application programming environments but don't travel well outside computer memory. When considering data science tasks and objectives the transition from object hierarchies to data structures (and vice versa) is not always straightforward. In this short course we explore how some programming languages, data formats, database API's and web frameworks handle hierarchical classes.

Reading Time: 3 min.
Summary In this short course we explore how some programming languages, data formats, database API’s and web frameworks handle hierarchical classes. Content Object-oriented programming and techniques (OOP) such as using classes and inheritance are common in many application programming environments but alas don’t “travel well” outside computer memory. The potentially intricate relationships of objects (both the data they hold and the meaning and possible uses of the data) are not easy to transfer (except of-course by full replication of code and data).
Introduction to the EBA NPL Templates

Introduction to the EBA NPL Templates

Reading Time: 3 min.
Summary The Open Risk Academy course NPL270672 is a CrashCourse introducing the EBA NPL Templates. Content We start with the motivation for the templates and the domain of credit data (to which NPL data belongs). We discuss three core classes that capture the essence of lending operations from a lenders point of view (Counterparty, Loan, Collateral). Next we explore classes that capture events in the lending relationship lifecycle (which we term NPL Scenarios).
