Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Buick Rendezvous of an older model year to newer model years
since older vehicles have been in service longer and thus are expected to have more problems.
In order to compare the reliability across Rendezvous model years, we use the PPMY index which is defined as the
problems reported per thousand vehicles per Year.
A smaller PPMY index indicates greater reliability of the given model year cars.

PPMY = P / S / Y * 1000,

where P = total problems reported during the life of a Buick Rendezvous 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 results are shown in Table 3.

Another way to measure the reliability across the model years of the Buick Rendezvous
is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
