Bentley Continental 2015: MOT failure rate for its age

5.8% of 4,966 MOT tests of the Bentley Continental first registered in 2015 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 89.5 (95% CI 79.2–99.9; 100 = normal for this model at that age): the 2015 Bentley Continental fails less often than other build years of the same model at the same age.

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
