My question is in regards to the optional convergence settings and how to determine when to change them. Noted in JMP user manual, default values for maximum iterations and convergence limit are 100 and .00000001, respectively. It continues to say that it is important to address these when you have a very large data set. My data contains 4267 rows. First of all, what do these mean? And should I change one or both to account for my large dataset?
