📈 PPMY Index and Problem Occurrence Trend

In our research we use the PPMY index to compare the reliability of vehicles. The PPMY index of a certain model is defined as the problems reported per thousand vehicles per Year. The total sales of the 2011 Mercury Mariner in the United States are 8,581 units [1]. If the total number of problems reported by Mercury Mariner owners in the last 15 years is 117, and the age of the vehicle is 15, the PPMY index can then be calculated as

      PPMY Index = 117 / 8,581 / 15 * 1000 = 0.91.
