Irving John Good (sometimes also named Jack ) is a British statistician born the December 9th 1916. Its competence in the field of the probabilities led it to work in the team of cryptographes of Bletchley Park. It was also developer in this center of the Ordinateur Colossus. It achieved a work founder in the field of the methods bayésiennes.

Biography

Its name was in fact Isidore Jacob Gudak . Student with Cambridge, it left doctor in 1941 there and was immediately integrated into the team of Bletchley Park, where it worked in close cooperation with Alan Turing. After the end of the war, it started to write an abundance of technical publications on the probabilities and the Inférence bayésienne, initially at the university of Manchester, then in various academic functions and of defense.

In 1967 it emigrated with the the United States, where he became professor at the university of Virginia (registering his car " facetiously; 007 IJG").

It published several books on the theory of probability and fact part of the group which imposed little by little the approach bayésienne on parity with the “traditional” interpretation of the probabilities.

Its name is often associated with the concept of weight of testimony ( weight off obviousness ), sometimes also named obviousness in French and noted Ev ( p ), with the following correspondence:

$Ev\; (p)\; =\; 10\; \backslash ,\; \backslash \; log\_\; \{10\}\; \backslash \; frac\; \{p\}\; \{(1-p)\}.$

however, professor Good always denied the paternity of this representation. He affirmed it discovered by Alan Turing which had baptized it log-odds , and independently by other researchers of which Jeffreys .

He is also known for his collection, permanently updated, of partly-baked ideas : intuitions not completely formalized, but which seemed to him promising. He also played a driving role in association Mensa.
