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 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...

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-...
