G.U. Yule (1871–1951) worked from 1892 at University College London under Karl Pearson, and from 1912 to 1931 at Cambridge. He published An Introduction to the Theory of Statistics in 1911, the 11th and subsequent editions of which were coauthored by M.G. Kendall. He contributed to the theory of regression, correlation, genetics, epidemiology, and time series, and developed a coefficient of association for 2 × 2 tables. He described what is now usually known as Simpson's paradox for association in a 2 × 2 × 2 tables. He introduced the simple birth process in the study of evolution.
