The Exponentially Weighted Moving Average (EWMA) is an alternative decision statistic to the standard ?two in a row? rule. The EWMA is a decision statistic that the OBD II regulations allow under certain circumstances. This presentation will review the EWMA implementation guidelines that were established by CARB in order to meet the requirements for alternative statistical decision making processes as described in section (d) (2.2.6) of 1968.2 (Light and Medium Duty OBD) and section (d)(2.2.2)(C) of 1971.1 (Heavy Duty OBD).
