Stochastic regression models on the safety perception on board cruise ships

Abstract

The paper evaluates the perception of safety by cruise companies on board a ship and its organizational management. The approach on the probability of a negative event incurring on shipping companies, passengers and environment affecting safety and it requires adequate and well-timed procedures on board. The methodology is based on negative binomial regression model on cross sectional data observed in t period based on frequencies of the events. The variables considered are collision, death, gastrointestinal norovirus, mechanical problems, fire, wounded, and general accident as dependent variable. This model reflects the condition that the event happens not infrequently in a certain period of time.
