Segmented regression analysis is a powerful statistical method ... WebWhat does 'interrupted' mean? Prism reports 'interrupted' in two situations: • Nonlinear regression is iterative and the maximum number of iterations is specified in the Method tab, with 1000 being the default. With data that don't really define all the parameters in the model, Prism can just keep iterating until it hits the limit.
