Biography

Nick Cox is interested in statistical applications within geography, including exploratory data analysis, graphics, smoothing, fitting of probability distributions, circular statistics and spatial analysis. Within geomorphology, hydrology and climatology his research has ranged from morphometry and modelling of hillslope, glacial and karstic forms, through analysis of precipitation distributions (e.g. the CSEP model developed with Professor Mike Kirkby of Leeds), to study of temperature variations in the Durham University Observatory record. Nick has developed software in various statistical and mathematical languages, including Stata, Awk and J. He is well-known in the Stata community as a prolific program writer, Chair of Stata London User Meetings (1997, 2000, 2002), former Associate Editor of the Stata Technical Bulletin, Executive Editor of the Stata Journal, and a frequent contributor to Statalist. Some of his programs have been incorporated in Stata 6.0 (1999), 7.0 (2001) and 8.0 (2003) and many others are available at the link below.

A long-established interest in the history, methodology and philosophy of geomorphology is currently expressed in joint editorial work on the forthcoming History of the Study of Landforms, volume 4. Nick is also Book Review Editor of Earth Surface Processes and Landforms and an Associate Editor of the Journal of Statistical Software.
