Problem Note 59844: Other than for simulations, transition matrices are not handled properly in analyses that have multiple horizons
In SAS® High-Performance Risk, multiple-horizon analyses handle transition matrices properly only for simulations.
Here are some examples.
Example 1
Say that a scenario analysis has 1-, 2-, or 3-day horizons and is associated with a project containing a simulation analysis that has 1-, 3-, and 7-day horizons. Instead of using the 1-day, 2-day, and 4-day transition matrices from the simulation analysis, 1-day transition matrices should be used for each horizon in the scenario analysis.
Example 2
Another scenario analysis has 3-, 9-, and 24-month horizons and is associated with a project without a simulation. Instead of returning errors about not finding those horizons, 3-month, 6-month, and 15-month transition matrices should be used for these horizons.
Errors
Most cases of this issue return errors similar to the following.
ERROR: A transition matrix for the requested horizon 1_DAY cannot be found.
ERROR: The project has no interval. This is required for non-model-based TRANSITION MATRICES.
Some cases do not return errors but might return incorrect values because of incorrect horizons.
