摘要
In this paper, we consider the density estimation problem from independent and identically distributed (i.i.d.) biased observations. We develop an adaptive wavelet hard thresholding rule and evaluate its performance by considering risk over Sobolev balls. We prove that our estimation attains a sharp rate of convergence and show the optimality. MSC: 49K40, 90C29, 90C31.
