Hi all,
i am using xmelogit to estimate the model where some IV are categorical.
when i am trying to use IV which are categorical predictors with more
then 2 levels (i.e. not just 0/1 - those are added without problems)
e.g. i.status , where status values are A to F (encoded as numbers)
i receive a following message:
"numerical derivatives are approximate
flat or discontinuous region encountered"
what does it mean?
i dont use those variables correctly?
thank you
