Tobit models are extended to allow threshold values which depend on individuals’ characteristics. In such models, the parameters are subject to as many inequality constraints as the number of observations, and the maximum likelihood estimation which requires the numerical maximisation of the likelihood is often difficult to be implemented. Using a Bayesian approach, a Gibbs sampler algorithm is...

Relatively recent research has illustrated the potential that tobit regression has in studying factors that affect vehicle accident rates (accidents per distance traveled) on specific roadway segments. Tobit regression has been used because accident rates on specific roadway segments are continuous data that are left-censored at zero (they are censored because accidents may not be observed on a...

The censored regression model and the Tobit model are standard tools in econometrics. This paper provides a formal asymptotic theory for dynamic time series censored regression when lags of the dependent variable have been included among the regressors. We derive fading memory properties of the model under the assumption that the regression error is strong mixing. We show the formal asymptotic ...

Realized volatility of stock returns is often decomposed into two distinct components that are attributed to continuous price variation and jumps. This paper proposes a tobit multivariate factor model for the jumps coupled with a standard multivariate factor model for the continuous sample path to jointly forecast volatility in three Chinese Mainland stocks. Out of sample forecast analysis show...

In order to explore the impact of financial factors on the real economy, many researchers are analyzing the relationship between finance and real economic activity using new theories and approaches. This paper focuses on the relationship between financial soundness and corporate R&D activities on a regional scale. By measuring regional financial performance using data series including periods o...

Tobit regression is used to analyze market shares for a cross section of 273 insurers operating in 1990. Lines of business analyzed include personal auto liability and physical damage insurance, homeowners multiperil, commercial general liability, workers compensation, and commercial multiperil. After controlling for size and other factors, evidence indicates that direct writing insurers have c...
