Hello to everyone.
I'm fitting a glm.nb model to a count data. I'm using about 8
predictive
variables.
Once a run the script I do get a result but it tells me that the
iteration
limit has been reached.
Most regression functions have a control parameter that can increase
the maximum number of iterations, but you provided no code so all is
guesswork from here.
So, can i trust the results given by the model?
Probably not. Some functions will not even record estimates if they
have failed the convergence tests.
Could it be a multicollinearity problem?
Could be.
Thank you for taking the time to help me.
