Biography and education

He was "born in India to a family of very modest means."^[1]

He obtained a B.A. in mathematics from Andhra University and, in 1957, an M.A. in statistics from Bombay University.^[1][2]

He came to the United States as a Fulbright Scholar to the Economics department of the University of Chicago.^[1]

In 1963, he completed his Ph.D. in the Department of Economics at the University of Chicago with a dissertation written under the supervision of Zvi Griliches.

Maddala published over 110 scholarly papers and wrote 12 books covering most of the emerging areas of econometrics. His 1983 book titled Limited Dependent and Qualitative Variables in Econometrics is now regarded as a classic and seminal text for advanced studies in econometrics.^{[citation needed]}

In econometrics methodology, Maddala's key areas of research and exposition included distributed lags, generalized least squares, panel data, simultaneous equations, errors in variables, income distribution, switching regressions, disequilibrium models, qualitative and limited dependent variable models, self-selection models, outliers and bootstrap methods, unit roots and cointegration methods, and Bayesian econometrics. In empirical economics, Maddala contributed to the areas of consumption, production and cost functions, money demand, regulation, pseudo-data, returns to college education, housing market discrimination, survey data on expectations, and risk premia in future markets.^[2]
