For analyzing non‐ignorable missing and left‐censored longitudinal data, we have proposed to extend the theory of random effects tobit regression model to weighted random effects tobit regression model. The weights are computed on the basis of inverse probability weighted augmented methodology. An ...

Other researchers have followed that study to model crash rates and injury severities by using the Tobit regression (Anastasopoulos et al., 2012b; Debnath et al., 2014; Islam and Hernandez, 2015; Xu et al., 2014) and also implemented random effects (Chen et al., 2014) and Bayesian ...

This study also explores the use of crash rate instead of crash frequency as dependent variable of the regression model, to understand more especially the effect of this choice on the significance of the covariates. A random-parameters tobit regression model showed that the significance of some ...
The model estimation results show that spatial and temporal effects and their interactive effects are significant and that the spatial and interactive effects have strong correlations across injury severities. The proposed model outperforms a multivariate random-parameters Tobit model and a multivariate ...
Significant temporal effects are found in all of the temporal models, and the inclusion of temporal correlation considerably improves the goodness of fit of the multivariate random parameters Tobit regression, according to the results of deviance information criteria (DIC) and Bayesian R-2, indicating...
