Professorship of Statistics at Columbia University in New York in the spring of 1949. In between this Roy returned to India and became Head of the Department of Statistics at the University of Calcutta during the academic year 1949–50. Roy joined Bose as full Professor of Statistics in the Statistics Department at the University of North Carolina at Chapel Hill. S. N. Roy had 15 doctorate students there from 1950 till 1963. To commemorate his Birth Centenary an International Conference on "Multivariate Statistical Methods in the 21st Century: The Legacy of Prof. S.N. Roy" was held at Kolkata, India during 28–29 December 2006. The Journal of Statistical Planning and Inference published a special issue for celebrating the Centennial of Birth of S. N. Roy. Personal life Roy was married to Bani Roy and had four children, Prabir, Subir, Tapon and Sunanda. He died while on holiday in Jasper, Canada. Selected publications Potthoff, R. F. and Roy, S. N.
