Problem Note 48033: Potentially incorrect results when using transformation methods and Delta-Normal analysis
 |  |  |  |  |
In SAS® Risk Dimensions, an interaction between the covariance matrix for a Delta-Normal analysis and a transformation method might result in incorrectly perturbed risk factor values in some market states. The following conditions describe how this problem might occur.
- The value of an instrument depends on risk factor 1 (rf1).
- The value of rf1 is set in a transformation method and is dependent on risk factor 2 (rf2).
- The risk factors rf1 and rf2 are not in the covariance matrix.
There are no warnings or errors. There are no workarounds.
