Sir David Cox, full name Sir David Roxbee Cox (born 15 July 1924 in Birmingham, Warwickshire [now West Midlands]) ), a British statistician known for his proportional hazards model.

Cox attended St John’s College, Cambridge, and worked for the Royal Aircraft Company in Farnborough from 1944 to 1946. From 1946 to 1950 he worked at the Wool Industry Science and Technology Research Association in Leeds, and in 1949 obtained a PhD in Statistics at the University of Leeds. From 1950 to 1955 he was Assistant Lecturer in Mathematics at the University of Cambridge. In 1956, he became Professor of Statistics at Birkbeck College, London, and in 1961 he became a Professor at the College. From 1966 to 1968 he was Professor of Statistics at Imperial College London. He became Dean of Nuffield College, Oxford University in 1988 and retired in 1994.

The statistical domain of survival analysis involves the time interval between the occurrence of a specific event, such as a mechanical failure or patient death. The rate at which failure occurs or a patient dies is called the hazard function. In the Cox proportional hazards model introduced in 1972, Cox proposed a hazard function that is divided into a time-dependent part and a time-independent part.

Distinguishing time-dependent input from time-independent input greatly simplifies the analysis of medical data, and Cox models are widely used in medical research. In 1990, Cox was awarded the General Motors Foundation for Cancer Research Kettering Award, an honor for outstanding contributions to cancer care.

Cox was knighted in 1985. He became a Fellow of the Royal Society in 1973 and was awarded the Copley Medal in 2010. He has authored books on many aspects of statistics, including The Theory of Random Processes (with HD Miller, 1965), Theoretical Statistics (with DV Hinkley, 1974), Survival Data Analysis (with David Oakes, 1984) and Principles of Statistical Inference (2006).
