Wilfrid Dixon

Wilfrid Joseph Dixon (born December 13, 1915 in Portland , Oregon, USA; † September 20, 2008 ) was an American statistician , known for his work on non-distribution statistics, serial correlation and the analysis of incomplete data.

Dixon received a BA in Mathematics from Oregon State College in 1938 , an MA in Mathematics from the University of Wisconsin a year later, and a Ph. D. Further Contributions to the in 1944 under the direction of Samuel Stanley Wilks at Princeton University Theory of Serial Correlation as a doctoral thesis. From 1942 to 1943 he taught at the University of Oklahoma, from 1946 to 1955 at the University of Oregon and from 1955 at the University of California at Los Angeles (UCLA), where he was Professor Emeritus from 1986. At UCLA, he was instrumental in creating the Department of Biostatistics. He organized the department of biomathematics at the medical school, which he headed from 1967 to 1974. From 1974 to 1980 he was a member of the USA-USSR working group on software. Dixon contributed significantly to the creation of the first general statistics software package (BMD, Biomedical Computer Programs, later BMDP Statistical Software). He organized the Statistical Computing Section at both the American Statistical Association (ASA) and the International Statistics Institute. In 1992 he received the Wilks Memorial Award .

Dixon married twice, first Eva Milne (daughter of mathematician William Edmund Milne ), after her death Glory, with whom he fathered two daughters. Two of the 14 grandchildren became biostatisticians.
