<P> Sankhya, the statistical journal published by ISI, was founded in 1933, along the lines of Karl Pearson's Biometrika . Mahalanobis was the founder editor . Each volume of Sankhya consists of four issues; two of them are in Series A, containing articles on theoretical statistics, probability theory and stochastic processes, and the other two issues form the Series B, containing articles on applied statistics, i.e. applied probability, applied stochastic processes, econometrics and statistical computing . </P> <P> According to India Education Review, no Indian university is in the world's top 200 universities . The ascribed ranking of ISI is 386 . The web ranking of this institute, according to 4ICU (4 International Colleges and Universities), is 1693 . According to the web ranking published by Webometrics Ranking of World Universities, ISI currently holds the world rank of 2086 . In the subject-wise academic world ranking of Computer Science, Indian Statistical Institute features in 101--150 category . The Indian Statistical Institute, Kolkata is ranked 2nd in Computer Science research by mean citation rate, p - Index, h - index among all universities in India . </P> <P> Over the years, researchers of ISI made fundamental contributions in various fields of Statistics such as Design of Experiments, Sample Survey, Multivariate statistics and Computer Science . Mahalanobis introduced the measure Mahalanobis distance which is used in multivariate statistics and other related fields . Raj Chandra Bose, who is known for his contributions in coding theory, worked on Design of Experiments during his tenure at ISI, and was one of the three mathematicians, who disproved Euler's conjecture on orthogonal Latin squares . Anil Kumar Bhattacharya is credited with introduction of the measures Bhattacharyya distance and Bhattacharya coefficient . Samarendra Nath Roy is known for his pioneering contributions in multivariate statistics . Among colleagues of Mahalanobis, other notable contributors were K.R. Nair in Design of experiments, Jitendra Mohan Sengupta in Sample Survey, Ajit Dasgupta in Demography and Ramkrishna Mukherjea in Quantitative Sociology . C.R. Rao's contributions during his association with ISI include two theorems of Statistical Inference known as Cramér--Rao inequality and Rao - Blackwell Theorem, and introduction of orthogonal arrays in Design of Experiments . Anil Kumar Gain is known for his contributions to the Pearson product - moment correlation coefficient with his colleague Sir Ronald Fisher at the University of Cambridge . </P> <P> In 1953, India's first indigenous computer was designed by Samarendra Kumar Mitra who headed the Computing Machines and Electronics Laboratory at ISI Calcutta . </P>
