Learn how the quality of OBD thresholds can be improved with a robust statistical analysis of the passing and failing data used in threshold determination. Using a statistical method for threshold determination as a basis for comparison, Senior Calibration Engineer Tony Gullitti of Robert Bosch, LLC will present how logistical regression can be applied to the threshold determination. Time and scope permitting, the machine learning methods of Gaussian analysis and dimensionality reduction for threshold determination will be explored.
