Order statistics in overlapping samples, moving order statistics and U-statistics
Statistical Laboratory, Iowa State University Ames, Iowa, U.S.A.
Let X1, X2, ... be a sequence of independent random variables with common distribution function F(x). Also let Xy:n(i) (i = 1,2, ...) denote the rth order statistic in (Xi..., Xi+n1). An expression is obtained for cov (Xr:n1(1), Xs:n2(n1 + 1-c)) in terms of the first two moments of order statistics in a sample of n'=n1+n2 c drawn from F(x). This result is used to study the behaviour of order statistics in moving samples and to unify certain results for linear functions of order statistics expressible as U-statistics.
