摘要
Consider a sequence (X-n) of independent and identically distributed random variables taking nonnegative integer values, and call X-n a record if X-n > max(X-1,..., Xn-1). By means of martingale arguments it is shown that the counting process of records among the first n observations, suitably centered and scaled, is asymptotically normally distributed.
