could you please explain to me in two to three sentences what the following info in my output means (or give me a hint, where to find it in your book)?
NO CONVERGENCE. SERIOUS PROBLEMS IN ITERATIONS. CHECK YOUR DATA, STARTING VALUES AND MODEL.
I already tried absurdly high iteration numbers myself (although I stopped trying as soon as I reached 5000). Reading what you wrote in this thread, I will try some more but IŽd still like to really better understand what it is, that tries to converge and what I try to give a better chance to for being able to converge.
