The aim of this paper is to evaluate the Passenger Satisfaction (PS) starting from quality factors (punctuality, safeness, staff aspect and conduct, modal integration, etc.). Carrying out two or more ways contingence tables, crossing the overall satisfaction (PS) and the quality factors we can study the dependency between the overall satisfaction and quality factors. In particular, the partition of Marcotorchino index for a three-way contingency table with one, two and three ordered categorical variables (Beh E.J., Simonetti B., D'Ambra L., 2007) will allow us to analyze the asymmetric and ordinal structure of the data and to pick up the nonlinear relationship within the data. To complement the survey Ordered Non-Symmetric Correspondence Analysis (ONSCA) will be carried out.

Abstract
The aim of this paper is to evaluate the Passenger Satisfaction (PS) starting from quality factors (punctuality, safeness, staff aspect and conduct, modal integration, etc.). Carrying out two or more ways contingence tables, crossing the overall satisfaction (PS) and the quality factors we can study the dependency between the overall satisfaction and quality factors. In particular, the partition of Marcotorchino index for a three-way contingency table with one, two and three ordered categorical variables (Beh E.J., Simonetti B., D'Ambra L., 2007) will allow us to analyze the asymmetric and ordinal structure of the data and to pick up the nonlinear relationship within the data. To complement the survey Ordered Non-Symmetric Correspondence Analysis (ONSCA) will be carried out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
