Mahalanobis and made significant contributions to the development of statistical theory and its applications in agriculture and economics. He later moved to the United States and worked at the University of Pittsburgh and the Pennsylvania State University, where he collaborated with S.N. Roy and W.G. Cochran. Rao also held visiting positions at several prestigious institutions, including the University of California, Berkeley, the University of Chicago, and the Harvard University. He was a fellow of the American Statistical Association, the Institute of Mathematical Statistics, and the International Statistical Institute.

● Contributions to Statistics

Rao made significant contributions to the field of statistics, including the development of the Cramér-Rao bound, the Rao-Blackwell theorem, and the Fisher-Rao metric. His work on linear algebra and calculus has had a profound impact on the development of statistical theory and its applications in various fields, including economics, biology, and engineering. Rao's contributions to statistical inference have been widely recognized, and he has written several influential books on the subject, including Linear Statistical Inference and Its Applications and Statistics and Truth. He has also made significant contributions to the development of multivariate analysis and time series analysis, and has worked on the application of statistical methods in medicine, psychology, and social sciences.

● Awards and Honors

Rao has received numerous awards and honors for his contributions to statistics, including the National Medal of Science from the National Science Foundation, the Padma Vibhushan from the Government of India, and the S.S. Wilks Memorial Award from the American Statistical Association. He has also been elected as a fellow of several prestigious organizations, including the Indian National Science Academy, the Indian Academy of Sciences, and the International Statistical Institute. Rao has received honorary degrees from several universities, including the Andhra University, the Osmania University, and the University of Pune. He has also been awarded the Mahalanobis Memorial Medal from the Indian Statistical Institute and the Gupta Memorial Medal from the Calcutta Statistical Association.

● Legacy
