13679 - A binary or categorical covariate with no events in one level may cause monotone likelihood convergence problems resulting in huge standard errors. Categorical or binary covariates with no events in one level typically lead to convergence problems from a condition known as "monotone likelihood". The FIRTH option, first available in SAS9.2 is a potential remedy. http://support.sas.com/kb/13/679.html, 21KB |
