Analysis of Severe Injury Accident Rates on Interstate Highways Using a Random Parameter Tobit Model
This paper presents an econometric analysis of the effects of price support program and stocks on price dynamics and price volatility. Considering a price support program as a censoring scheme, market prices are specified as a dynamic Tobit model under time varying volatility. The model is applied to the U.S. nonfat dry milk market, based on monthly data for the period of 1970-2000. The econome...
This paper presents an econometric analysis of the effects of price support programs and stocks on price dynamics and price volatility. Considering a price support program as a censoring mechanism, market prices are specified as a dynamic Tobit model with time varying volatility. The model is applied to the U.S. nonfat dry milk market to examine the impact of market liberalization on price dyna...
abstract unbalance using of chemical fertilizers cause decline the soil quality and fertility, environmental pollution and specially soil and water resources pollution. the use of animal manure is a replacement to chemical fertilizers. therefore, recognizing of demographic, technical-extensional and agronomic affect on farmer's decision making process to use of animal manure will have important...
This paper provides a computationally practical simulation estimation for the dynamic panel Tobit model with large categories of dependence structures. The simulation estimators are conducted through correlated random effects approach. The log-likelihood function is simulated and maximized through procedures based on a recursive algorithm formulated by GHK and Gibbs sampling simulators. The ini...
Purpose – The purpose of this paper is to examine the relationship between firms’ value drivers and their intellectual capital (IC). Design/methodology/approach – The health care sector (GICS 35) firms listed in the S&P500 were used to build a research censoring Tobit model by adopting financial data to determine value drivers. Findings – The results of the study show that innovation capital, c...
Ground water nitrate concentrations on Nantucket Island, Massachusetts, were analyzed to assess the effects of land use on ground water quality. Exploratory data analysis was applied to historic ground water nitrate concentrations to determine spatial and temporal trends. Maximum likelihood Tobit and logistic regression analyses of explanatory variables that characterize land use within a 1000-...
