MINI Roadster 2013: MOT failure rate for its age

20.9% of 1,753 MOT tests of the MINI Roadster first registered in 2013 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 115.2 (95% CI 103.4–127.0; 100 = normal for this model at that age): the 2013 MINI Roadster fails more often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.

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.
