Problem Note 55202: The UDS statement in PROC MCMC fails to recognize multidimensional arrays as parameters
 |  |  |  |  |
If you use an ARRAY statement in the MCMC procedure to define parameters with a multidimensional array, the UDS statement fails to treat the array parameter as valid syntax. An error message such as the following is issued:
ERROR: The parameter X has an UDS option, but it is not the OUTARG
variable in any of the subroutines called in the program.
For example, the following set of statements within PROC MCMC should be supported:
array beta[4] beta1-beta4;
uds BetaUpdater(beta, s2, XtX, XtY, sigma2);
parms beta /uds;
prior beta ~ mvn(mu, Sig);
In the above, the ARRAY statement is used to generate beta, an array parameter that is sampled with UDS option in the PARMS statement.
