We investigate the limit behavior of the Lk-distance between a decreasing density f and its nonparametric maximum likelihood estimator f¿n for k¿1. Due to the inconsistency of f¿n at zero, the case k=2.5 turns out to be a kind of transition point. We extend asymptotic normality of the L1-distance to the Lk-distance for 1¿k1, we show that the Lk-distance between f and f¿n is asymptotically equivalent to the Lk-distance between Un and g.
