  Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the older model year Volkswagen Jetta to a new one in terms of the problems reported since older vehicles have been in service longer and more problems should be reported. In order to compare the reliability across Jetta model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index implies a better reliability for the model year under study.

    PPMY = P / S / Y * 1000

Where P = total problems reported during the life of a Volkswagen Jetta model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).

The result is shown in Table 3.
