In this paper, we apply time series techniques for panel data to the environmental Kuznets curve (EKC) model. Within … for sulphur emissions using a panel data set for 74 countries over 30 years. Using individual unit root tests, we find … confirmed by panel unit root tests that find that the panel series are integrated. Individual cointegration tests show that EKC …

In many scientific studies, the response variable bears a generalized nonlinear regression relationship with a certain covariate of interest, which may, however, be confounded by other covariates with unknown functional form. We propose a new class of models, the partly parametric generalized...

Proportional hazards analyses assume that the magnitude of mortality risk for a predictor variable remains proportional over time. In a time-dependent model, the explanatory variable violates this assumption, and repeat observations are required to accommodate the change in risk that occurs over...

Background: An important issue in prediction modeling of multivariate data is the measure of dependence structure. The use of Pearson's correlation as a dependence measure has several pitfalls and hence application of regression prediction models based on this correlation may not be an...
