Hi
Thanks for the new NEGBIN command.
I have tried it out using the PATENTS data in Verbeek (ch 7.3.2).
However, using the Model menu it breaks down.
Likewise if I try to use the NEGBIN1 alternative (--model1) in the console I get
the message "The convergence criteria not met." 
A bug?
Best regards,
Lars
