โฆ Synopsis
Let {x,x~
; n >\_ 1} be a sequence of i.i.d, random variables. Set Sn = X1 + X2 + โข .. +Xn and M,~ = maxk 1. By using the strong approximation method, we obtain that for any -1
if and only if EX = 0 and EX 2 < oo, which strengthen and extend the result of Gut and Sp~taru [1],
where N is the standard normal random variable. Furthermore, L2 convergence and a.s. convergence are also discussed.

The corresponding moderate deviation principle follows. The Central Limit theorem has been recently obtained by Pang, Lin and Hwang [T.X. Pang, Z.Y. Lin, K.S. Hwang, Asymptotics for self-normalized random products of sums of i.i.d. random variables, J. Math. Anal. Appl. 334 (2007) 1246-1259].
Let \(\left\{X, X_{n} ; \vec{n} \in \mathbb{N}^{d}\right\}\) be a field of independent identically distributed real random variables, \(0<p<2\), and \(\left\{a_{\bar{n}, \bar{k}} ;(\bar{n}, \bar{k}) \in \mathbb{N}^{d} \times \mathbb{N}^{d}, \bar{k} \leqslant \bar{n}\right\}\) a triangular array of r
