Gradient Convergence Criterion
Use this field to specify a number to be used for determining the convergence for iterations on a gradient to numerically solve a general linear mixed model .
The number here is multiplied by 10 -8 and added to the NLOPTIONS statement in PROC GLIMMIX. Refer to the SAS documentation for PROC GLIMMIX for more information.
Note : If you see errors regarding NEWRAP convergence in the SAS log after you run an ANOVA analytical report, you should consider increasing this number. This will effectively reduce the restrictive criterion and help you avoid this convergence error.
To Specify a Value for the Gradient Convergence Criterion:
