Problem Note 64336: The GLIMMIX procedure might produce incorrect ILINK results for estimates involving a random effect

DetailsCodeAboutRate It

PROC GLIMMIX produces incorrect results for the inversely linked estimate of the mean and its standard error when these conditions are met:

  • The DIST=MULTINOMIAL and LINK=GLOGIT options are specified in the MODEL statement,
  • A RANDOM statement is specified,
  • A random effect is specified in the ESTIMATE statement, and
  • The ILINK option is specified in the ESTIMATE statement

If the CL option is specified in the ESTIMATE statement, the confidence interval for the inversely linked mean is also incorrect.

There is one exception, and the problem does not occur for multirow estimates when the random effect is continuous.

See the Full Code tab for examples that illustrate the problem. 

There is no circumvention for this problem.
