icon-email BUI KHOI DAM

Abstract

Let (Xn)n1 be a stationary, strong mixing sequence of random variables with EXn=0, EXn2=1 and let Bσ(X1,X2,,Xn,) with P(B)>0. In this note we establish an estimation for the quantity
Δn(B)=suptR|P(Sn.(ESn2)1/2<t|B)Φ(t),
where Φ(t) is a standard normal distribution function and Sn=i=1nXi.
