Raghu Raj Bahadur (30 April 1924 – 7 June 1997) was an Indian statistician considered by peers to be "one of the architects of the modern theory of mathematical statistics".[1][2]
Biography
[edit]Bahadur was born in Delhi, India, and received his BA (1943) and MA (1945) in mathematics from St. Stephen’s College, University of Delhi .[3][4] He received his doctorate from the University of North Carolina under Herbert Robbins in 1950 after which he joined University of Chicago. He worked as a research statistician at the Indian Statistical Institute in Calcutta from 1956 to 1961. He spent the remainder of his academic career in the University of Chicago. He was a cousin to Madhur Jaffrey.[5]
Contributions
[edit]He published numerous papers[6] and is best known for the concepts of "Bahadur efficiency"[7] and the Bahadur–Ghosh–Kiefer representation (with J. K. Ghosh and Jack Kiefer).[8]
He also framed the Anderson–Bahadur algorithm[9] along with Theodore Wilbur Anderson which is used in statistics and engineering for solving binary classification problems when the underlying data have multivariate normal distributions with different covariance matrices.
Legacy
[edit]He held the John Simon Guggenheim Fellowship (1968–69)[10] and was the 1974 Wald Lecturer of the IMS.[4] He was the President of the Institute of Mathematical Statistics during 1974–75[10] and was elected a Fellow of the American Academy of Arts and Sciences in 1986.[11]
