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]
Biography[edit]
Bahadur was born in Delhi, India, and received his BA (1943)[2] and MA (1945)[2] in mathematics from University of Delhi. 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.[3]
Contributions[edit]
He published numerous papers[4] and is best known for the concepts of "Bahadur efficiency"[5] and the Bahadur–Ghosh–Kiefer representation (with J. K. Ghosh and Jack Kiefer).[6]
He also framed the Anderson–Bahadur algorithm[7] 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)[8] and was the 1974 Wald Lecturer of the IMS.[2] He was the President of the Institute of Mathematical Statistics during 1974–75[8] and was elected a Fellow of the American Academy of Arts and Sciences in 1986.[9]
