Jayanta Kumar Ghosh or Jaẏanta Kumāra Ghosha (Bengali: জয়ন্ত কুমার ঘোষ, born May 23, 1937) is an Indian statistician, currently emeritus professor at Indian Statistical Institute and a professor of statistics at Purdue University.

Education

He obtained a B.S. from Presidency College, then affiliated with the University of Calcutta, and subsequently a M.A. and a Ph.D. from the University of Calcutta. He started his research career in the early 1960s, studying sequential analysis as a graduate student in the department of statistics at the University of Calcutta.

Among his best-known discoveries are the Bahadur-Ghosh-Kiefer representation (with R. R. Bahadur and Jack Kiefer) and the Ghosh-Pratt identity.

His research contributions fall within the fields of:

• Bayesian inference
• Asymptotics
• Modeling and model selection
• High dimensional data analysis
• Nonparametric regression and density estimation
• Survival analysis
• Statistical genetics
