Estimate Transition Probabilities
Transition probabilities offer a way to characterize the past changes in credit quality of obligors (typically firms), and are cardinal inputs to many risk management applications. Financial Toolbox™ supports the estimation of transition probabilities using both cohort and duration (also known as hazard rate or intensity) approaches using transprob
and related functions.
Functions
transprob | Estimate transition probabilities from credit ratings data |
transprobbytotals | Estimate transition probabilities using totals structure
input |
transprobgrouptotals | Aggregate credit ratings information into fewer rating categories |
transprobprep | Preprocess credit ratings data to estimate transition probabilities |
Topics

Use estimation transition probabilities to evaluate credit migration histories.
- Visualize Transitions Data for transprob
This example shows how to visualize credit rating transitions that are used as an input to the
transprob
function. - Credit Quality Thresholds
Use transition probabilities by transforming them into credit quality thresholds.
- Credit Rating by Bagging Decision Trees
This example shows how to build an automated credit rating tool.
