The GLIMMIX Procedure

Convergence Status

The Convergence Status table contains a status message describing the reason for termination of the optimization. The message is also written to the log. The ODS name of the Convergence Status table is ConvergenceStatus, and you can query the nonprinting numeric variable Status to check for a successful optimization. This is useful in batch processing, or when processing BY groups, such as in simulations. Successful optimizations are indicated by the value 0 of the Status variable.
