Problem Note 48045: PROC MCMC exits unexpectedly
 |  |  |  |  |
PROC MCMC exits without any explanation when the hyperparameters of a random effect are in the functional form of a regression model. For example the random effect alpha is defined such that its hyperparameters are constructed using a regression model:
mu = a * x1 + b * x2;
random alpha ~ n(mu, sd=1) subject=i;
This definition of the hyperparameter mu causes PROC MCMC to terminate.
There is no circumvention for this problem.
