Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: This paper presents a probit-based discrete-continuous model for analyzing relationships between multiple endogenous variables of different types. The probit-based discrete-continuous model formulation offers the ability to model the joint relationship between a discrete choice and continuous choice variable while accommodating a multivariate normally distributed error covariance structure. The paper presents the model formulation and estimation method. In addition, the paper develops and presents the formulation of a non-nested hypothesis test for comparing alternative discrete-continuous model specifications where the model specifications are not nested in one another. The model formulation and non-nested test were applied to an analysis of the relationship between the time-of-day choice and time allocation or duration of maintenance activities. Model systems were estimated separately for commuter and non-commuter samples drawn from the 2000 Switzerland microcensus of travel. Model estimation results show that error covariances are significant for commuter models of maintenance activity timing and duration. Non-nested model comparisons indicate that the model specification where time-of-day choice affects activity duration offers a statistically superior goodness-of-fit in comparison to the model specification where activity duration affects time-of-day choice. These findings lend credence to the notion that the joint relationship between timing and duration adopted in activity-based model systems should be one in which the activity schedule or agenda drives activity time allocation or duration.
