Simulate Credit Rating Migration Risk
The creditMigrationCopula
object takes as
input a portfolio of credit-sensitive positions with a set of counterparties
and performs a copula-based, multifactor simulation of credit rating
migrations. Counterparty credit rating migrations and subsequent changes
in portfolio value are calculated for each scenario and several risk
measurements are reported. For more information on credit migration,
see Credit Rating Migration Risk.

This example shows a common workflow for using a
creditMigrationCopula
object to measure credit migration risk for a credit portfolio. - Credit Rating Migration Risk
The migration-based multi-factor copula (
creditMigrationCopula
) is similar to thecreditDefaultCopula
object.
