The Amoroso kernel density estimator (Igarashi and Kakizawa ) for non-negative data is boundary-bias-free and has the mean integrated squared error (MISE) of orderO(n− 4/5), wherenis the sample size. In this paper, we construct a linear combination of the Amoroso kernel density estimator and its derivative with respect to the smoothing parameter. Also, we propose a related multiplicative estimator. We show that the MISEs of these bias-reduced estimators achieve the convergence ratesn− 8/9, if the underlying density is four times continuously differentiable. We illustrate the finite sample performance of the proposed estimators, through the simulations.
