Research Area

Mathematical statistics, measure theory

Retired as of July 1, 1999, I am still semi-active in the department. I am not active in research.

My research concerned the application of decision theory methods to statistical problems to try and characterize completely good and bad methods of estimation and testing. Useful decision theory methods can involve development of inequalities, compactification of spaces, and study of the way sequences of measures converge.
