Abstract: Let {Xn,n≥1} be an independent and identically distributed continuous random variables,let {Ln,n≥1} and {μn,n≥1} be th

e record times sequence and corresponding counting process. By using the central limit theorem,the moment inequalities and the Berry-Essee

n inequalities of the record times and its counting process,a general result of precise asymptotics for the record times and corresponding counting process wer

e obtained for the boundary function and quasi-weight function.

Keywords: counting process; record times; precise asymptotics; general form
