Abstract
A sequential version of Chernoff-Savage linear rank statistics is introduced as a basis for inference. The principal result is an invariance principle for two-sample rank statistics, i.e., under a fixed alternative the sequence of sequential linear rank statistics converges weakly to a Wiener process. The domain of application of the theorem is quite broad and includes score functions which tend to infinity at the end points much more rapidly than that of the normal scores test. The method of proof involves new results in the theory of multiparameter empirical processes as well as some new probability bounds on the joint behavior of uniform order statistics. Applications of weak convergence are explored; in particular, the extension of the theory of Pitman efficiency to the sequential case.

Some invariance principles for mized rank statistics and induced order statistics and some application

TL;DR: The structural affinity of mixed rank statistics and linear combinations of functions of concomitants of order statistics (or induced order statistics) is examined in this paper, and some weal as well as strong invariance principles for these statistics are studied.

Sequential Detection of a Positive Signal

TL;DR: In this paper, the authors consider the problem of detecting a positive signal in additive noise, where the observations are assumed to be discrete-time, and make a decision based on the observations, whether the signal is absent or present.

Non-parametric sequential tests for symmetry

TL;DR: In this paper, the authors consider the construction of sequential tests by means of the familiar linear signed-rank statistics and derive a functional limit theorem for two-sample linear rank statistics and heuristically derived the concept of Pitman efficiency in the sequential case.

Nonparametric Repeated Significance Tests

TL;DR: In this article, the authors consider a clinical trial intended for studying the effectiveness of two competing drugs for a particular treatment, patients undergoing the treatment are allotted to one of the drugs and statistical conclusions are drawn on the basis of the responses of these drugs.

Limit Theorems for Stochastic Processes

TL;DR: The authors consider a sequence of processes such that the multivariate distribution of the processes of the process (i.e., the process of finding the distribution of a set of processes) tends to the multi-dimensional distribution of that process.

Convergence Criteria for Multiparameter Stochastic Processes and Some Applications

TL;DR: In this paper, the authors derived thehentsov-Billingsley type fluctuation inequalities for stochastic processes whose time parameter ranges over the $q$-dimensional unit cube and established weak convergence results for such processes.
