A prediction model for COPD readmissions: catching up, catching our breath, and improving a national problem

Frequent COPD exacerbations have a large impact on morbidity, mortality and health-care expenditures. By 2020, the World Health Organization expects COPD and COPD exacerbations to be the third leading cause of death world-wide. Furthermore, In 2005 it was estimated that COPD exacerbations cost the U.S. health-care system 38 billion dollars. Studies attempting to determine factors related to COP...

The fear of another deadly pandemic is ever imminent, and this issue’s Select looks at recent efforts to understand this ever-shifting virus. From efforts aiming to predict its geographical spread to those that elucidate the basic viral biology and host response, researchers are looking for new ways to stay ...

Catching Up Faster in Bayesian Model Selection and Model Averaging

Bayesian model averaging, model selection and their approximations such as BIC are generally statistically consistent, but sometimes achieve slower rates of convergence than other methods such as AIC and leave-one-out cross-validation. On the other hand, these other methods can be inconsistent. We identify the catch-up phenomenon as a novel explanation for the slow convergence of Bayesian metho...
