Estimate Transition Probabilities

Estimate change in credit quality, model transition probabilities from credit rating data

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.
