The focus of most of these writers was on classical inference applied tofairly standard situations, such as linear models, survey sampling and designedexperiments as explored in the decision-theoretic framework of Wald, whichgave a clear infrastructure for both frequentist and Bayesian analysis. This includedthe novel methodology and approach of sequential analysis, introducedby Wald in the 1950s, and the behavior of rank-based nonparametric tests andestimates based on them as developed by Hodges and Lehmann. Both of thesedevelopments were pushed by World War II work. Robustness considerationswere brought to the fore through Tukey’s influential 1958 paper “The Futureof Data Analysis” and then the seminal work of Hampel and Huber.6.3 My work before 1979My thesis with Erich Lehmann at the University of California (UC) Berkeleywas on a robust analogue of Hotelling’s T 2 test and related estimates.I then embarked on a number of contributions to many of the topics mentioned,including more robustness theory, Bayesian sequential analysis, curveestimation, asymptotic analysis of multivariate goodness-of-fit tests, and thesecond-order behavior of rank test power and U-statistics. Several of the papersarose from questions posed by friends and colleagues. Thus, some generalresults on asymptotic theory for sequential procedures as the cost of observationtended to zero was prompted by Yossi Yahav. The second-order analysis ofnonparametric tests grew out of a question asked by Hodges and Lehmann intheir fundamental paper published in 1970 (Hodges and Lehmann, 1970). Thequestion was picked up independently by van Zwet and myself and we thendecided to make common cause. The resulting work led to the development ofsecond-order theory for U-statistics by van Zwet, Götze and myself; see Bickel(1974) and subsequent papers. The work on curve estimation originated fromaquestionposedbyMurrayRosenblatt.I even made an applied contribution in 1976 as a collaborator in the analysisof “Sex bias in graduate admission at Berkeley” which appeared in Science(Bickel et al., 1975). Thanks to my colleague David Freedman’s brilliant textbookStatistics, it garnered more citations than all my other work. This wasinitiated by a question from Gene Hammel, Professor of Anthropology andthen Associate Dean of the Graduate Division.Two opportunities to work outside of UC Berkeley had a major impact onmy research interests, the second more than the first, initially.
