Fisher's influence on me

This is the 100th year anniversary of Fisher's 1918 paper "The correlation between relatives on the supposition of Mendelian inheritance" (Transactions of the Royal Society of Edinburgh 1918, 52 pp 899-438). Fisher's work has had a strong influence on today's genetic epidemiology and this brief autobiographical note highlights a few of the ways his influence on me has affected the field. Although I once took a course of lectures from Fisher, it was mainly his writings that influenced my statistical thinking. Not only did the concept of maximum likelihood appeal to me, but also the concepts of interclass and intraclass correlations, discriminant analysis, and transforming semiquantitative scores to minimize interactions-all topics I first learned about from the 11th edition of his book on Statistical Methods for Research Workers. This, together with a few serendipitous events that shaped my career, had a large influence on me and hence also on the field of genetic epidemiology.
