what is the difference between zip and zicb can you use zip model instead of binomial model what model fails to converge in zip what model does zinb use which model converge which model has the lowest aic, bic, and p value, but not zero which is easier to use zero inflation zinb or zip what model would fail to converge does zip model converge what model fails to converge zinb is zip binomial how does zinb model work what model fails to converge how to find out what model fails why is zinb model not converged which model fails to converge to the zinb model does zip model converges with zinb does zinb converge why does zip model fail to converge why does zip model fail
