Abstract: | Summary For a sequence of independent and identically distributed random vectors, with finite moment of order less than or equal to
the second, the rate at which the deviation between the distribution functions of the vectors of partial sums and maximums
of partial sums is obtained both when the sample size is fixed and when it is random, satisfying certain regularity conditions.
When the second moments exist the rate is of ordern
−1/4 (in the fixed sample size case). Two applications are given, first, we compliment some recent work of Ahmad (1979,J. Multivariate Anal.,9, 214–222) on rates of convergence for the vector of maximum sums and second, we obtain rates of convergence of the concentration
functions of maximum sums for both the fixed and random sample size cases. |
