Parameters | Expression Parameters | Pseudo-Likelihood Convergence Criterion

The number specified here is multipled by 10-8 and the product is specified as the optional parameter PCONV in PROC GLIMMIX. The GLIMMIX procedure applies this criterion to fixed-effects estimates and covariance parameter estimates.Refer to the SAS documentation for PROC GLIMMIX for more information.Note: If you see non-convergence notes regarding PCONV in the log after you run ANOVA process, you can increase this number to have a less restrictive criterion and thus avoid this convergence error. You should experiment with different values to achieve a reasonable restrictive criterion and strike a reasonable balance between convergence errors and reliability.
