Abstract:

Using compactly supported wavelets, Gine and Nickl [Uniform limit theorems for wavelet density estimators, Ann. Probab. 37(4) (2009) 1605-1646] obtain the optimal strong L-infinity(R) convergence rates of wavelet estimators for a fixed noise-free density function. They also study the same problem by spline wavelets [Adaptive estimation of a distribution function and its density in sup-norm loss by wavelet and spline projections, Bernoulli 16(4) (2010) 1137-1163]. This paper considers the strong L-p(R) (1 <= p <= infinity) convergence of wavelet deconvolution density estimators. We first show the strong L-p consistency of our wavelet estimator, when the Fourier transform of the noise density has no zeros. Then strong L-p convergence rates are provided, when the noises are severely and moderately ill-posed. In particular, for moderately ill-posed noises and p = infinity, our convergence rate is close to Gine and Nickl's.
