Debabrata Basu

Debabrata Basu (Bengali: দেবব্রত বসু) (5 July 1924 – 24 March 2001) was a mathematical statistician who made fundamental contributions to the foundations of statistics. Basu invented simple examples that displayed some difficulties of likelihood-based statistics and frequentist statistics; Basu's paradoxes were especially important in the development of survey sampling. In statistical theory, Basu's theorem established the independence of a complete sufficient statistic and an ancillary statistic.

Born in Dacca, Bengal, in unpartitioned India (now in Bangladesh), Basu was associated with the Indian Statistical Institute in India, and Florida State University in the United States.
