SUPPORT / SAMPLES & SAS NOTES
Problem Note 45184: Proxy bucket scenario simulation results might be incorrect when one or more bucket weights are zero or are essentially zero (for example, 1E-10)
 |  |  |  |  |
In SAS® OpRisk VaR, the VaR simulation results might be incorrect if you use a proxy bucket scenario when one or more of the bucket weights are zero or are very small. For example, a zero might be specified as bucket weight. But the final weight that is calculated might be very close to, but not quite zero (for example, 1E-10). Then during simulation, there might be a loss event for that bucket. There are no error messages.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
The workaround is to not use proxy bucket scenarios that have weights that are zero or are very small.
