An analytical framework is developed in this study for panel analysis of travel behavior. The model system involves two endogenous variables; one is discrete and the other continuous. It is assumed that the errors associated with each of the endogenous variables are serially correlated, and that the errors for the two endogenous variables are also correlated. The model components are singly estimated in a sequential manner using correction terms which account for the correlations among the errors. The approach is an extension of the method used to correct for sample selectivity and applied previously in the transportation field to examine attrition bias in panel data, vehicle acquisition and utilization, and activity engagement and time allocation.
