I have been tackling some "big picture" questions related to using statistical methods in practice.

My major focus is on assessing the differences between explanatory, predictive and descriptive modeling and statistical modeling in terms of the statistical modeling process (from data collection and goal definition to model use). My paper To Explain or To Predict? discusses the distinction from a statistical point of view. The paper Predictive Analytics in Information Systems Research examines the value of predictive modeling to theory building, testing, and validation, illustrated in information systems research which is monopolized by explanatory modeling.

I have also been working on answering a question that many of my non-statistician colleagues have asked me: how to deal with inference (and p-values) in analyses of large samples. Some work in progress is available in our working paper Is More Always Better? Larger Samples and False Discoveries.

A third topic that I am working on with Ron Kenett is the notion of Information Quality, which is the potential of a dataset to answer a particular scientific/practical question using a given data analysis method. Our  paper On Information Quality formalizes the concept in terms of definition, characterization, and assessment.
