The sequential allocation of particles in the multinomial scheme is considered. The multinomial trials are conducted until the frequences of k, 1 < k < N, outcomes become for the first time no less thanthe corresponding levels. Decomposable statistics (DS) are studied, where N is the number of outcomes, QJ, 1 < j < N t are functions of an integer-valued argument and fy-is the frequency of the jth outcome at the stopping time. The exact and asymptotic results related to L^k and their various specializations are presented and some applications to the statistical inference for the multinomial scheme are given.
