Decision Analysis to Advance Environmental Sustainability
Decision analysis provides a robust framework for complex decisions related to environmental sustainability and conservation, including for energy and water, fisheries and wildlife management, agri…
New Views on Effect of Recycled Aggregates on Concrete Compressive Strength
This paper presents an in-depth study on the effect that composition and properties of recycled coarse aggregates from previous concrete structures, together with water/cement ratio (w/c) and a rep…
Accounting Quality and Trade Credit
We examine whether firms with low accounting quality are more likely to use trade credit as a source of financing. Because of their advantages in overcoming information frictions, suppliers are mor…
Modeling Multivariate Volatilities via Latent Common Factors
Volatility, represented in the form of conditional heteroscedasticity, plays an important role in controlling and forecasting risks in various financial operations including asset pricing, portfoli…
Smooth Tests of Copula Specifications
We present a family of smooth tests for the goodness of fit of semiparametric multivariate copula models. The proposed tests are distribution free and can be easily implemented. They are diagnostic…
Online Updating of Survival Analysis
When large amounts of survival data arrive in streams, conventional estimation methods become computationally infeasible since they require access to all observations at each accumulation point. We…
