                                 Combines different types of algorithms to get reliable and robust assessment between CAE and Test Data signals in the form
                                    of time history.    Includes corridor, phase, magnitude, and slope which are calculated independently and then combined to
                                    give an overall ISO rating.    The error calculation can be biased towards either the measured time history (Test) or the
                                    computed (CAE) time history, with the former being most common.
