'''Raghu Raj Bahadur''' (30 April 1924 – 7 June 1997) was an [[India]]n [[statistics|statistician]] considered by peers to be "one of the architects of the modern theory of mathematical statistics".<ref>{{cite web | url=http://chronicle.uchicago.edu/970612/bahadur.shtml | title=Obituary: Raghu Raj Bahadur, Statistics | work=The University of Chicago Chronicle | date=12 June 1997 | accessdate=8 October 2018 }}</ref>

==Contributions==

He published numerous papers<ref>[https://stat.uchicago.edu/people/in-memoriam/] Bahadur's CV hosted at University of Chicago</ref> and is best known for the concepts of "[[Bahadur efficiency]]"<ref>[http://www.math.binghamton.edu/arcones/prep/pv.pdf] A paper about Bahadur efficiency</ref> and the [[Bahadur–Ghosh–Kiefer representation]] (with [[J. K. Ghosh]] and [[Jack Kiefer (statistician)|Jack Kiefer]]).<ref>{{cite journal|last=Lahiri|first=S. N|title=On the Bahadur—Ghosh—Kiefer representation of sample quantiles|journal=Statistics & Probability Letters|year=1992|volume=15|issue=2|pages=163–168|doi=10.1016/0167-7152(92)90130-w}}</ref>

He also framed the [[Anderson–Bahadur algorithm]]<ref>Classification into two [[multivariate normal distribution]]s with different [[covariance matrices]] (1962), T W Anderson, R R Bahadur, ''Annals of Mathematical Statistics''</ref> along with [[Theodore Wilbur Anderson]] which is used in statistics and engineering for solving binary classification problems when the underlying data have [[multivariate normal distribution]]s with different [[Covariance matrix|covariance matrice]]s.
