st: glm "backed up"

[Ashlie Delshad <abelmore@purdue.edu>]

Hello everyone,

I am attempting to run a negative binomial model through the glm command so 
that I can include HAC standard errors (these is not an option through the 
nbreg command); however, whenever I run the model I keep getting output that 
shows the iteration and loglikelihood and then in parentheses it says (backed 
up) and it will not give me any output.  This happens when I run the negative 
binomial model through the glm model with or without specifying HAC standard 
errors - however, I can run the model (without HAC standard errors) through the 
nbreg command without any problems. Any ideas on how I can get this to work 
through glm?

Thanks,
