Abstract

Objectives:To study the asymptotic theory of the randomly wieghted partial sum process of powers of k-spacings from the uniform distribution.Methods:Earlier results on the distribution of the uniform incremental randomly weighted sums.Methods:Based on theorems on weak and strong approximations of partial sum processes.Results and conculsions:Our main contribution is to prove the weak convergence of weighted sum of powers of uniform spacings.

Highlights

  • Let 0 = U(0) ≤ U(1) ≤ U(2) ≤⋅⋅⋅≤ U(n−1) ≤ U(n) = 1 be the order statistics of a random sample of size (n-1) from the U(0,1) distribution

Summary

INTRODUCTION

Let 0 = U(0) ≤ U(1) ≤ U(2) ≤⋅⋅⋅≤ U(n−1) ≤ U(n) = 1 be the order statistics of a random sample of size (n-1) from the U(0,1) distribution. Be arbitrary but fixed and assume that n=mk. The U (0,1) k-spacings are defined as. Be iidrv with E(Xi)=μ, Var(Xi)=ó2
