Residential self-selection effects in an activity time-use behavior model

Residential Self-Selection Effects in an Activity Time-Use Behavior Model

This study presents a joint model system of residential location and activity time-use choices that considers a comprehensive set of activity-travel environment (ATE) variables, as well as sociodemographic variables, as determinants of individual weekday activity time-use choices. The model system takes the form of a joint mixed Multinomial Logit–Multiple DiscreteContinuous Extreme Value (MNL–M...

Modeling Residential Self-Selection in Activity-Travel Behavior Models: Integrated Models of Multidimensional Choice Processes

A Copula-Based Approach to Accommodate Residential Self-Selection Effects in Travel Behavior Modeling

The dominant approach in the literature to dealing with sample selection is to assume a bivariate normality assumption directly on the error terms, or on transformed error terms, in the discrete and continuous equations. Such an assumption can be restrictive and inappropriate, since the implication is a linear and symmetrical dependency structure between the error terms. In this paper, we intro...

DESIGNING AN OPTIMIZATION MODEL FOR PREVENTING THE WASTE TIME IN THE ACTIVITY CYCLE OF AN ORGANIZATION

This article proposes an optimization model for preventing the waste of time in the educational and research activities' cycle of an organization such as a university. For this purpose and in order to increase efficiency and prevent the waste of time; the graph theory models have been used. The educational and research activities diagrams of a supposed university is drawn by the use of graphs t...

Residential self-selection bias in the estimation of built environment effects on physical activity between adolescence and young adulthood

BACKGROUND Built environment research is dominated by cross-sectional designs, which are particularly vulnerable to residential self-selection bias resulting from health-related attitudes, neighborhood preferences, or other unmeasured characteristics related to both neighborhood choice and health-related outcomes. METHODS We used cohort data from the National Longitudinal Study of Adolescent ...
