摘要:
The wavelet estimations have made great progress when an unknown density function belongs to a certain Besov space. However, in many practical applications, one does not know whether the density function is smooth or not. It makes sense to consider the mean L-p-consistency of the wavelet estimators for f is an element of L-p (1 <= p <= infinity). In this paper, the authors will construct wavelet estimators and analyze their L-p(R) performance. They prove that, under mild conditions on the family of wavelets, the estimators are shown to be L-p (1 <= p <= infinity)-consistent for both noiseless and additive noise models.
