Subject:
The problem of large deviation probabilities for a large class of functionals of empirical measures was solved. This enabled to calculate for the first time the Bahadur, Chernoff and Hodges–Lehmann efficiencies of numerous nonparametric statistics for goodness-of-fit, homogeneity, symmetry and independence testing. The notion of local optimality domain was introduced and investigated for many nonparametric statistics. Some original characterization theorems connected with the property of local optimality were found. In a series of joint works with E.V.Ponikarov we studied the large deviation asymptotics of Chernoff type for U- and V-statistics with general kernels. Some generalizations of arc-sine law were obtained jointly with E. Orsingher. Jointly with N. Henze we introduced and studied new goodness-of-fit tests based on the integrated empirical process.
