The paper studies various response transformation models for discrete choice and categorical data. These response transformation models are fitted to binary response data on beverage choice. Several models are compared, and the best model is selected using AICs and deviances. The transformations include extensions of the widely used Box-Cox transformation to Normality for continuous data to categorical data. The econometric techniques employed in the paper are widely applicable to the analysis of count, binary response, and duration types of data encountered in business and economics.

C. He is an expert in Business Statistics at the Westlaw Roundtable Group. He has published more than 70 articles in some of the most prestigious statistics and econometrics journals. His research on semi-parametric econometrics, missing data problems, nonlinear statistical and econometric models, robust statistical procedures, limited dependent variables and duration data analysis has been published in Econometric Theory, The American Statistician, International Journal of Advanced Statistics and Probability, Statistica Neerlandica, Statistical Papers, Sankhya, Economics e-journal, Bulletin of Economic Research, Economics Letters, Applied Economics Letters, and Empirical Economics Letters. He serves on the editorial boards of several statistics and economics journals. His research has been cited in statistics and econometrics textbooks and journals as well as a widely-used volume on statistical distributions. He received the Outstanding Professor Award from California State University, Los Angeles in 2003 for excellence in teaching and research. He has been listed in Who’s Who among American Teachers and Educators (11th Edition, 2007).
