Sir Ronald Fisher

Sir Ronald Aylmer Fisher, FRS (February 17, 1890 – July 29, 1962) was an evolutionary biologist, geneticist and statistician. He has been described by Richard Dawkins as "The greatest of Darwin’s successors," and the historian of statistics Anders Hald said "Fisher was a genius who almost single-handedly created the foundations for modern statistical science."

Biography

Fisher was born in East Finchley, London and obtained a B.A. degree in mathematics, not astronomy as is often said, from Cambridge University in 1912. In 1911 he was involved in the formation of the Cambridge University Eugenics Society. His studies of errors in astronomical calculations, together with his interests in genetics and natural selection, led to involvement in statistics.

From 1919 he worked at Rothamsted Experimental Station making contributions in statistics and genetics. In 1933 he became a professor of eugenics at University College London moving in 1943 to the Balfour chair of genetics at Cambridge. 1919 was a common year starting on Wednesday (see link for calendar). ...

He received various awards for his work and was made a Knight Bachelor by Queen Elizabeth II in 1952. He had a long running feud with Karl Pearson (he declined a post at the University of London), and later with Pearson's son E.S. Pearson. After retiring from Cambridge he spent some time as a research fellow at the CSIRO in Adelaide, Australia where he died in 1962.

Fisher's important contributions to both genetics and statistics are emphasized by the remark of L.J. Savage, “I occasionally meet geneticists who ask me whether it is true that the great geneticist R.A. Fisher was also an important statistician” (Annals of Statistics, 1976). Leonard Jimmie Savage (20 November 1917 - 1 November 1971) was a US mathematician and statistician. ...

Contributions to statistics

Fisher invented the techniques of maximum likelihood and analysis of variance, was a pioneer in the design of experiments, and originated the concepts of sufficiency, ancillarity, and Fisher information, making him a major figure in 20th century statistics. His article "On a distribution yielding the error functions of several well known statistics" presented Karl Pearson's chi-squared and Student's t in the same framework as the normal distribution and his own analysis of variance distribution z. Fisher's book Statistical methods for research workers showed how to use these distributions. See also Fisher's linear discriminator. In statistics, the method of maximum likelihood, pioneered by geneticist and statistician Sir Ronald A. Fisher, is a method of point estimation, that uses as an estimate of an unobservable population parameter the member of the parameter space that maximizes the likelihood function. ... In statistics, analysis of variance (ANOVA) is a collection of statistical models and their associated procedures which compare means by splitting the overall observed variance into different parts. ... The first statistician to consider a methodology for the design of experiments was Sir Ronald A. Fisher. ... In statistics, one often considers a family of probability distributions for a random variable X (and X is often a vector whose components are scalar-valued random variables, frequently independent) parameterized by a scalar- or vector-valued parameter, which let us call θ. ... In statistics, an ancillary statistic is a statistic whose probability distribution does not depend on which of the probability distributions among those being considered is the distribution of the statistical population from which the data were taken. ... In statistics, the Fisher information I(θ), thought of as the amount of information that an observable random variable carries about an unobservable parameter θ upon which the probability distribution of X depends, is the variance of the score. ...

Contributions to biology

Much of Fisher's contributions to statistics were based on biological data from Rothamsted. His work on the theory of population genetics also made him one of the three great figures of that field, together with Sewall Wright and J. B. S. Haldane, and as such was one of the founders of the neo-Darwinian modern evolutionary synthesis. His 1918 paper The Correlation Between Relatives on the Supposition of Mendelian Inheritance was the start of the modern evolutionary synthesis — a synthesis which he would later contribute much to in his 1930 book The Genetical Theory of Natural Selection. Population genetics is the study of the distribution of and change in allele frequencies under the influence of the four evolutionary forces: natural selection, genetic drift, mutation and migration. ... Sewall Green Wright (December 21, 1889 - March 3, 1988) was one of the primary founders of population genetics which led to the modern evolutionary synthesis. ... John Burdon Sanderson Haldane (November 5, 1892 - December 1, 1964), who normally used J.B.S. as a first name, was a geneticist born in Scotland and educated at Eton and Oxford University. ... The modern evolutionary synthesis (often referred to simply as the modern synthesis), neo-Darwinian synthesis or neo-Darwinism, brings together Charles Darwins theory of the evolution of species by natural selection with Gregor Mendels theory of genetics as the basis for biological inheritance. ... 1918 was a common year starting on Tuesday (see link for calendar). ... The Correlation Between Relatives on the Supposition of Mendelian Inheritance is a scientific paper by Ronald Fisher which was published in the Philosophical Transactions of the Royal Society of Edinburgh in 1918, (volume 52, pages 399—433). ...

Fisher information

Fisher introduced the concept of Fisher information in 1925, many years before Shannon's notion of entropy. Fisher information has been the subject of renewed interest in the last few years, both due to the growth of Bayesian inference in AI, and due to B. Roy Frieden's book Physics from Fisher Information, which attempts to derive the laws of physics from a Fisherian starting point. In statistics, the Fisher information I(θ), thought of as the amount of information that an observable random variable carries about an unobservable parameter θ upon which the probability distribution of X depends, is the variance of the score. ... 1925 was a common year starting on Thursday (link will take you to calendar). ...
