Sir David Cox FBA FRS

David Cox was a statistician who significantly advanced statistical analysis and its application. His paper introducing his proportional hazards model has some tens of thousands of citations. The best known application of this work is in analysing data from clinical trials; other applications include modelling failure of mechanical components.

David's model provides a means to work out which of many possible variables are predictive of a particular outcome that is related to the time that has passed. David's many other notable contributions included detailed studies of sequences of point events and work on experimental design.

Amongst his many awards, David received the Copley Medal, the Guy Medal in Gold of the Royal Statistical Society and the Kettering Prize for Cancer Research. He was Editor of the journal, Biometrika, from 1966 to 1991. He served as President of the Bernoulli Society for Mathematical Statistics and Probability, the Royal Statistical Society and the International Statistical Institute. He was knighted in 1985.

Sir David Cox FRS died on 18 January 2022.
