Abstract：
In the present investigation of high energy multiparticle production,the method of event by event ananysis has received wide interest. Inasmuch as the limited number of particles in a single event,an important problem is that the elimination of statistical fuctuations has to be worked out first of all. In the current literature,the elimination of statistical fuctuations has been only considered in lower order moments (not above the third order). In the present paper,the elimination of statistical fuctuations is studied in higher order moments and a general expression for the elimination of statistical fluctuations in the moments of arbitrary order is given.
