Within a method for predicting customer satisfaction for a transportation
vehicle there is measured for the transportation vehicle a Noise,
Vibration and Harshness (NVH) level within the transportation vehicle when
an engine which powers the transportation vehicle is operating at wide
open throttle. The method further provides for determining a customer
satisfaction value for a specific transportation vehicle by means of
interpolation or extrapolation from an existing correlation for a group of
transportation vehicles within the same class. Such a correlation is
obtained employing a Transformed Gamma Distribution (TGD) model or an
aggregate combination of Transformed Gamma Distribution (TGD) models.
