Publications and Technical Articles #

In addition to the peer-reviewed papers listed below, I also have written or collaborated on other articles and essays about a variety of topics.

White Papers #

Preparing data for analysis using R
A white paper on data exploration and treatment in R, including a survey of commonly encountered data issues and how to resolve them. I also briefly introduce vtreat, Win-Vector's R package for automated data treatment (CRAN distribution). This paper was generously sponsored by Microsoft Data Science.

Miscellaneous Technical Articles #

Articles that I've authored or contributed to that haven't been formally published. Roughly, in the order most recent first.

Fluid data reshaping with cdata: A discussion of data reshaping, and an introduction to the terminology we use to specify reshaping in the cdata R package (and the data_algebra Python package).

Coordinatized Data: A Fluid Data Specification: In which John Mount and I discuss why data structure (the logical form of records) is separate from data layout (the "physical" layout of data in rows and columns), and the implications of this observation for data reshaping.

vtreat: a data.frame Processor for Predictive Modeling: Describes the theory of data preparation behind vtreat, and demonstrates its use.

Comparing Apples And Oranges: A paper with John Mount on the limits of statistical inference in the Google AdSense market.

"Something out of Something": Improvisational Training for Emergency Managers: A white paper about improvisation, in the context of emergency management.
