Asymptotic normality of a nonparametric estimator of sample coverage
样本覆盖度非参数估计量的渐近正态性
This paper establishes a necessary and sufficient condition for the asymptotic normality of the nonparametric estimator of sample coverage proposed by Good [Biometrica 40 (1953) 237–264]. This new necessary and sufficient condition extends the validity of the asymptotic normality beyond the previously proven cases.
