SUPPORT / SAMPLES & SAS NOTES
Problem Note 47870: COPULA option in PROC MODEL may cause incorrect simulation values when dimension of SDATA matrix is smaller than total number of equations
 |  |  |  |  |
If you specify Monte Carlo simulation with the RANDOM= option on the SOLVE statement, and the COPULA option is also specified, and if the dimension of the covariance matrix in the SDATA= data set is smaller than the number of equations to be solved, then those variables that are not in the SDATA= data set incorrectly get perturbed as well. The simulated values in the OUT= data set are also incorrect.
There is no circumvention for this problem.
