Abstract：For the nonparame tric smoo th PL-estimator Fn , the smooth PL-process n(Fn -F)can be uniformly represented by a smooth experiential process plus a neg ligible remainder term w hen the data are subject to random left truncation.In this paper , w e improved the result o f Zhou Yang(1996)and made the representation more ex plicit in statistics .The lawof itera ted log arithm (LIL)was established from this representation .
