【Abstract】 Let the service time{X_n,n≥1}be a nonnegative nonstationary negatively associated(NA)random variable sequence and N(t)be the renewal process generated by {X_n,n≥1}.By the results of the precise asymptotics for the partial sums of NA sequence and the relations between S_n and N(t),that is {N(t)<n}= {S_n>t},we proved the precise asymptotics for renewal processes of nonstationary NA sequences.更多还原
