A series of statistical analyses was performed to determine the degree of 'correlation' that exists between two specific short tests (STs) and the Federal Emission Certification Test Procedure (FTP) for new vehicles. This work was performed to determine if 'reasonable correlation with certification test procedures' exists; this is a condition precedent to the promulgation of regulations that impose the in-use warranty provisions of Sec. 207(b) of the Clean Air Act of 1970 upon the motor vehicle manufacturers. The basis for the analyses was ST and FTP test data from three 100-vehicle fleets located in (a) Chicago, Illinois, (b) Houston, Texas, and (c) Phoenix, Arizona. Each of the vehicles in these fleets was tested by the FTP, the Federal Short Cycle, and the Federal 3-Mode. Two different statistical analysis methods were used to assess 'correlation'--a conventional correlation analysis, and a contingency table analysis.
